Answer:

see below

Step-by-step explanation:

5(x + y) + 6(x − y)

Distribute

5x+ 5y + 6x -6y

Combine like terms

11x -y

(5x − 3y) − x + 3x − 5y

Combine like terms

5x -x +3x   -3y -5y

7x -8y

4(x + y) − 3(x + y)

Distribute

4x +4y -3x -3y

Combine like terms

x -y

x − 4x + 6y + (14x − 5y)

Combine like terms

x -4x +14x    +6y -5y

11x    +y

3x + 3y + 2(2x − y)

Distribute

3x+3y +4x -2y

Combine like terms

7x +y

What is the surface area? 5 mm 4 mm 5 mm 6 mm 6 mm square millimeters​
mylen [45]

Answer:

6 x 4 = 24, 24 divided by 2 = 12(area of 1 triangle)

12 x 2(two triangles) = 24

5 x 6 = 30(area of 1 slanted rectangle)

30 x 2(two rectangles) = 60

6 x 6 = 36(area of bottom square)

Add all given AREAS:

24 + 60 + 60 = 144 mm2 is your answer.

Thomas buys a cardboard sheet that is 8 by 12 inches. Let x be the side length of each cutout. Create an equation for the volume
Alekssandra [29.7K]
Answer: Your equation would be y = x(12 - 2x)(8 - 2x).

The volume of a rectangular prism is V = LWH. The initial length and width are given as 12 and 8, however that makes the height 0.

If we cut out the corners, they would be the length of x. When we cut out the corners, we are subtract the length x from both ends of the length and width.

So now our measurements are:
Length: 12 - 2x
Side: 8 - 2x
Height: x

Multiply them altogether and you have your equation. Then, you can use your equation to find any measurements that you need.
