What two numbers have a product of 18 and a sum of 11?​

Answers

Answer 1

Answer: 2 and 9

2*9 = 18

2+9 = 11

=======================================================

Explanation:

You can find this through trial-and-error. You're basically looking for factors of 18 which add to 11. Something like 6 and 3 won't work since 6+3 = 9, but 2 and 9 works since 2+9 = 11.

Or you can use algebra as shown below.

--------------

Let x and y be the two numbers. They have a product of 18, so x*y = 18.

They also have a sum of 11, meaning x+y = 11. Solving for y leads to y = 11-x

Plug this into xy = 18 and we get x(11-x) = 18 which becomes -x^2+11x = 18

Now subtract 18 from both sides to arrive at the equation -x^2+11x-18 = 0.

Let's use the quadratic formula to solve.

We'll plug in a = -1, b = 11, c = -18

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(11)\pm\sqrt{(11)^2-4(-1)(-18)}}{2(-1)}\\\\x = \frac{-11\pm\sqrt{49}}{-2}\\\\x = \frac{-11\pm7}{-2}\\\\x = \frac{-11+7}{-2}\ \text{ or } \ x = \frac{-11-7}{-2}\\\\x = \frac{-4}{-2}\ \text{ or } \ x = \frac{-18}{-2}\\\\x = 2\ \text{ or } \ x = 9\\\\[/tex]

If x = 2, then y = 11-x = 11-2 = 9

If x = 9, then y = 11-x = 11-9 = 2

Both values of x lead to the same pair of values overall, meaning that 2 and 9 are the two values we're after.

2*9 = 18

2+9 = 11

Answer 2

The two numbers with a product of 18 and a sum of 11 are 2 and 9.

To find two numbers with a product of 18 and a sum of 11, we can set up a system of equations. Let the two numbers be x and y.

1. Product: xy = 18

2. Sum: x + y = 11

We can solve this system of equations simultaneously to find the values of x and y. One way to do this is to use substitution or elimination methods.

For instance, we can solve for y in the second equation: y = 11 - x

Now, substitute this value of y into the first equation: x(11 - x) = 18

Simplify and solve for x: x^2 - 11x + 18 = 0

By factoring or using the quadratic formula, we find two possible values for x: x = 2 or x = 9.

Now, substitute these values back into the equation y = 11 - x to find the corresponding values of y: If x = 2, y = 11 - 2 = 9; if x = 9, y = 11 - 9 = 2.

So, the two numbers with a product of 18 and a sum of 11 are 2 and 9.

Answer:

Many people have lost the true meaning of love. Love is a very important part of one's life, and if there is uncertainty, it should not be pursued. The true meaning of love is to be in a complete and total bond with each other and care for each other when others flee. While many people try to achieve love in other ways, such as seeking financial support or having someone to support them in ways that they should do on their own, is not the true meaning of love. The ideas stated in the last sentence would help relationships but would blur the overall meaning of love.

Write about Chinese culture essay
Has to be 100 words or more!!!​

Answers

Answer:

Chinese culture is one of the world’s oldest cultures, tracing back to thousands of years ago. Important components of Chinese culture includes ceramics, architecture, music, literature, martial arts, cuisine, visual arts, philosophy and religion.

Ethnic Groups-Officially there are 56 recognized ethnic groups in China, Han Chinese being the largest group. Many ethnic groups, though merge into Han identity, have maintained distinct linguistic and regional cultural traditions. Even within one ethnic group, there are probably diverse groups of people. Various groups of the Miao minority, for example, speak different dialects of the Hmong-Mie languages, Tai-Kadai languages, and Chinese, and practice a variety of different cultural customs. Typically each minority group has their own costumes, festivals and customs. For example, various marriage customs  are found among different minority groups. There is actually a museum that features marriage customs of ethnic groups-Guizhou Museum of Marriage Customs.

Religion-Confucianism and Taoism, later joined by Buddhism, constitute the “three teachings” that historically have shaped Chinese culture. There are no clear boundaries between these intertwined religious systems, which don’t claim to be exclusive, and elements of each enrich popular or folk religion. Folk or popular religion, the most widespread system of beliefs and practices has evolved and adapted since at least Shang and Zhou dynasties. During the period fundamental elements of a theology and spiritual explanation for the nature of the universe emerged. Basically, it consists in allegiance to the “shen”, a character that signifies a variety of gods and immortals, who can be deities of the natural environment of ancestral principles of human groups, concepts of civility, cultural heroes, many of whom feature in Chinese mythology and history. Recent surveys estimated that some 80% of Han Chinese practice some kind of Chinese folk religion and Taoism; 10-16% are Buddhists; 3-4% are Christians; and 1-2% are Muslims.

Chinese Medicine-Traditional Chinese medicine is built on a foundation of more than 2,500 years of Chinese medical practices that includes various forms of herbal medicine, acupuncture, massage, exercise and dietary therapy.  Its philosophy is based on Yinyangism,(the combination of Five Phases theory with Yin-Yang theory) which was later absorbed by Daoism. In general, disease is perceived as a disharmony or imbalance in the functions or interactions of yin, yang, meridians etc. between the human body and the environment. Therapy is based on which “pattern of disharmony” can be identified. Today Traditional Chinese medicine is widely used in China and is becoming increasingly prevalent in Europe and North America.

Chinese Family-Family has been a key component in society for thousands of years in China. Today, many aspects of Chinese life can be tied to honoring one’s parents or ancestors. Because of the focus on family, it is common for Chinese, even when fully grown with children of their own, to have many living generations of a family living under the same roof. Chinese family structure has traditionally been rigid and hierarchical. Many parents and grandparents now still expect their children/grandchildren to do as they are told. Now many Chinese families face challenges and contradictions to the old way of life that threaten its traditional stability. Many young workers have been drawn to bigger cities in the more prosperous regions in China to find better jobs with higher salaries. The young workers tend to send part of their salary to their parents who may still reside in small towns with much lower salaries. However, as they reaches 30 years old they face increasing pressure from their parents to marry and move back to their hometown.

Chinese Food-The history of Chinese food in China stretches back for thousands of years and has changed from period to period in each region according to climate, imperial fashions, and local preferences. The “Eight Cuisines” of China are Anhui, Cantonese, Fujian, Hunan, Jiangsu, Shandong, Sichuan, and Zhejiang cuisines. These styles are distinctive from one another due to factors such as availability of resources, climate, geography, history, cooking techniques and lifestyle. For example, Jiangsu cuisine favours cooking techniques such as braising and stewing, while Sichuan cuisine employs baking. Hairy crab is a highly sought-after local delicacy in Shanghai, as it can be found in lakes within the region. Peking duck and dim-sum are other popular dishes well know outside of China.

Please write a short summary on why the voting age should be lowered

Answers

Answer:

Lowering the voting age can lead to a long-term increase in voter turnout, bringing more citizens in touch with their government and pushing the government to better serve its people. Research shows that voting is habitual. A person who votes in the first election they are eligible for is likely to continue voting consistently, while someone who doesn’t will take several years to pick up the habit. It is clear that age 16 is a better time to establish a new habit than age 18, and data from places that have lowered the voting age shows that 16-year-olds do indeed vote at higher rates than older first-time voters.

Explanation:

Answer: It should not be.

Explanation:

Even though many young adults or teens have vary strong thoughts on how things should be. The young people may not believe these things for because that is what they are pressured to believe. Such as allowing a male to enter a woman's bathroom because the feel like a girl. Many young adults would not stop to think about how this would open the door to rapper's and such. There for I believe it should not be lowered below the age of 18 years.
