Can someone please help me with math.

Answer:

Solution: 36x2−9

Step-by-step explanation:

So, you always have to start with distrubuting which is basically dividing.

Heres the equation that I started with. You can do it differently of course.

36x2+18x-3(6x+3)

combine like terms.

36x2-9

, your solution will be

36x2-9

Answer:

2(m + [n)] + [1]

Step-by-step explanation:

(2m) + (2n + 1) =

= 2m + 2n + 1

= 2(m + n) + 1

= 2(m + [n)] + [1]

The simplification of the expression would be equal to 2(m + [n)] + [1].

Usually, simplification involves proceeding with the pending operations in the expression.

Like, 5 + 2 is an expression whose simplified form can be obtained by doing the pending addition, which results in 7 as its simplified form.

Simplification usually involves making the expression simple and easy to use later.

An even plus an odd equals an odd.

[tex](2m) + (2n + 1)\\= 2m + 2n + 1\\= 2(m + n) + 1\\= 2(m + [n)] + [1][/tex]

Answer:

Probably B or A

Step-by-step explanation:

Because learning about stingrays asking a question like that can tell you how many are left and how long you have to study them while they are here. and A because you wanna get to know their surroundings and what's better for them in an environment before you actually get to know about the stingrays, studying the environment can give you an idea of what to look for when you are diving in the ocean. Meaning you know exactly what to look for when diving so you can get as much information as you need.

Answer:

The house is 2000 meters from the school.

Step-by-step explanation:

Given that, when I have walked 20% of the way to school, I have 1200 meters more to walk than when I have 20% of the walk remaining, to determine how far, in meters, is it from my home to my school the following calculation has to be done:

100 - 20 = 80

80 = 20 + 1200

80 - 20 = 1200

60 = 1200

1200/60 = 20

20 x 100 = 2000

Therefore, the house is 2000 meters from the school.

Have a nice day noona/hyung

Answer: 24 hours - no; because depending on where you are on Earth, you have a  different amount of sunlight.

Step-by-step explanation:

The day-night cycle is a complete day or a complete rotation of the earth around its axis. This takes 24 hours which is why 24 hours is the length of a full day.

People around the world however, do not get the same amount of sunlight or darkness and this is because of where they are on Earth. Due to the way the planet is tilted on its axis, some areas see sunlight more than other in a period and others see more darkness.

The surface area of triangular prism is 281.68 square cm

Triangular Prism is a pentahedron and has nine distinct nets. The edges and vertices of the bases are joined with each other via three rectangular sides. The sides of the triangular prism, which are rectangular in shape are joint with each other side by side. All cross-sections parallel to the base faces are the same as a triangle. A triangular pyramid has four triangular bases unlike the triangular prism, joined with each other and all are congruent to each other.

We have,

The length of triangular prism(l)=13 cm

The height of triangular prism(h)= 5.1 cm

The base of triangular prism(b)= 6.8 cm

S1, S2, and S3 are the three edges (sides) of the base triangle=6.1 cm,6.8 cm and 6.1 cm

Perimeter of base(p)=S1+S2+S3

                             =6.1cm+6.8cm+6.1cm

                            =19cm

According to question,

We know the formula of The surface area of prism=(perimeter of base× length of prism)+(2×base area of prism)

                                          =(P ×l)+(2×[tex]\frac{1}{2}[/tex]×b ×h)

                                          =(19×13)+(6.8×5.1)

                                           = 247+34.68

                                           =281.68 square cm

The solutions of the system of equations are x = 45 and y = 5.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

The system of equations,

x = 9y  .... (1)

x-5y=20 ......(2)

Substituting the value of x from the equation 1 to equation 2,

we get,

9y - 5y = 20

4y = 20

y = 5

Then, x = 5(9) = 45

Therefore, the solutions of the equations are x = 45 and y = 5

Answer:

C

Step-by-step explanation:

Since all triangles' angles have a sum of 180 degrees, it can't be A, because that would make it 240 degrees. That leaves us with B and C. While B could be true, we don't know it for sure. Therefore, C is the correct answer because adding them should equal 60 degrees, which, adding them to the first angle (which was 120 degrees), would 180 degrees.
