What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given an expression (13n²+11n−2n⁴)+(−13n²−3n−6n⁴)
Let's simplify it step-by-step.
13n²+11n−2n⁴−13n²−3n−6n⁴
=> 13n²+11n−2n⁴−13n²−3n−6n⁴
Combine Like Terms:
=> 13n²+11n−2n⁴−13n²−3n−6n⁴
=> 8n - 8n⁴
=>n(2³ - n³)
Therefore, a Simplified form of expression (13n²+11n−2n⁴)+(−13n²−3n−6n⁴) in the standard notation is n(2³ - n³).

The ratio of boys to girls in a school is 4:5. How many boys are in the school if there are 720 students.
Answer:
There are 320 boys
Step-by-step explanation:
boys: girls : total
4 5 4+5 = 9
Take the total and divide by 9
720/9 = 80
Multiply each term by 80
boys: girls : total
4*80 5*80 9*80
320 400 720
There are 320 boys
Answer:
324 boys
Step-by-step explanation:
Add the ratio, 4+ 5 = 9 and divide 720 with nine. Then multiply that value, 81, with 4 to find the number of boys, and multiply with 5 to get the girls

OBC is a sector of a circle with centre o and radius 9cm work out the area of the shaded region as a percentage of the area of sector obc to 1 decimal place
Answer:
83.7 %
Step-by-step explanation:
To get the area of the shaded region, we will following these steps.
Step one: Get the area of the sector of the circle.
The area of the sector of the circle can be obtained using the formula:
[tex]Area = \frac{\theta}{360}\times \pi r^{2}[/tex]
Theta will be 60 degrees because triangle OAD is an equilateral triangle
Hence, [tex]Area = \frac{60}{360}\times \pi \times 9^{2}= 42.42cm^{2}[/tex]
Step Two: Get the area of the equilateral triangle
The area of the equilateral triangle can be got using the formula
[tex]Area = \frac{1}{2} Base \times Height[/tex]
The height of the triangle can be got by drawing an imaginary line bisecting the triangle into two parts and applying the Pythagoras' theorem to any of the resulting right-angled triangles formed.
This will be [tex]height =\sqrt{4^{2}-2^{2}} =3.46cm[/tex]
Thus [tex]Area = \frac{1}{2}\times 4\times 3.46=6.93cm^{2}[/tex]
Step Three: Subtract the area of the triangle from the area of the sector
Area of the shaded portion = [tex]42.42cm^{2}-6.93cm^{2}=35.49cm^{2}[/tex]
Step Four: Divide the area of the shaded portion by the area of the entire shape and multiply the result by 100:
Expressing the ratio of the two areas as a percentage, we have
[tex]\frac{35.49}{42.42} \times 100\approx 83.7 %[/tex] %

Answer:
Step-by-step explanation:
Firstly,
What is the mean?
The mean is where you add up all the number then divide the total by how many numbers there are.
8th number?

2. 5.7
3. 6.1
4. 2.3
5. 3.1
6. 4.5
7. 4.1
8. x
Opposite way:
4.1 + 5.7 + 6.1 + 2.3 + 3.1 + 4.5 + 4.1 = 29.9
(29.9 x) / (8) = 3.7375
3.7375 + x = 4.1375
4.1375 - 3.7375 = 0.4

Which inequality is represented by this graph?
Answer: C
Step-by-step explanation:
We can say that the equaiton of the line is -1/6x+1, considering that is in each answer choice. Than main part is the shading and inequality. If you look closely at the graph, the shading line is a dashed/dotted line. This means the shaded part does not equal the actual line. We can eliminate B and D.
Now, we are left with A and C. A is saying y< while C is saying y>. C is the correct answer because if you look at the shading, it it above the line, which is greater than. Therefore, the answer is C.

I need to know the answer for “x” please!
Answer:

Step-by-step explanation:
This can easily be solved by congruence.
Both triangles have the same proportions.
9.8 : 8.8 = (2 + 9.2) : (x + 8.8)
Because these are proportional, we can use and write this as if they were fractions.
9.8 / 8.8 = (2 + 9.2) / (x + 8.8)
multiply crosswise, gives:
9.8 * (x + 8.8) = (2 + 9.2) * 8.8
9.8 * x + 9.8 * 8.8 = (11.2) * 8.8
9.8 * x + 86.24 = 98.56
9.8 * x = 98.56 - 86.24
9.8 * x = 12.32
Divide left and right of the = sign by 9.8 gives,
x = 12.32 / 9.8
x = 1.2(571428)
x = 1.26 cm

Describe fully the single transformation that maps triangle a onto triangle b
Answer:
Triangle (A) reflected over the line y = x
Step-by-step explanation:
From the figure attached,
Coordinates of the vertices of triangle (A) are A(1, 4), B(1, 2) and C(2, 2)
After transformation of triangle A, coordinates of the vertices A', B' and C' of the image triangle (B) are,
A'(4, 1), B'(2, 1) and C'(2, 2)
Lets choose point A to find the rule of transformation,
A(1, 4) → A'(4, 1)
Rule → (x, y) → (y, x)
It shows triangle (A) has been reflected across a line y = x.
Therefore, triangle (A) maps onto triangle (B) when reflected over the line y = x.

Step-by-step explanation:
11.4-15.7 = -4.3
Answer:
A. -4.3 F
Step-by-step explanation:
Originally you started with 11.4 F, and the question said it decreased by 15.7 F so that basically means you subtract the final condition from initial,
11.4 F - 15.7 = -4.3 F, so at night it was -4.3 F cold.
If you think about this question in terms of apples. Originally I gave you 12 apples to keep for a day. When I returned home at 7pm the numbers of apples decreased by 8. So bascially my final apples will be 12- 8 = 4 apples remaining.

Consider this system of linear equations: y = –3x + 5 y = mx + b Which values of m and b will create a system of linear equations with no solution?
Answer:
m = - 3 and b = - 3.
Step-by-step explanation:
A system of linear equations will not have solutions if the two lines are parallel.
Two equations are parallel:
1. if their slopes (m) are equal
2. the y-intercep (b) are different.
As y = - 3x + 5, the value of m of the other equation, y = mx + b, in order to make a system with no solution, needs to be - 3, and the value of b need to be different to 5.
The only pair from the choices that meets that is the first option m = - 3 and b = -3.
Answer:
m = -3, b = 5
Step-by-step explanation:
The values m = -3 and b = 5, forms a linear equation: y = -3x + 5. This obviously coincides with the original equation given, and so will create a system of linear equations with no solution.
Telephone pole breaks and falls as shown. To the nearest foot, what was the

but its a triangle and in the bottom it has number 10 and in the long side of the triangle is 7
Answer:
Length of the pole = 12.2ft
Step-by-step explanation:
Hello,
According to your description, the pole against a wall of height 7ft and the distance between the base of the pole to the wall is 10ft.
See attached document for better illustration.
To solve this problem, we'll have to make use of pythagorean theorem
According to pythagorean theorem,
X² = y² + z²
X = ?
Y = 10ft
Z = 7ft
X² = 10² + 7²
X² = 100 + 49
X² = 149
X = √(149)
X = 12.2ft
The length of the pole is 12.2 ft
Unfortunately, the length of the pole does not corresponds with any of the answers above, but this is actually the right answer.
Good luck
