Answer:
Sarah use distributive property in Step 1.
Step-by-step explanation:
Consider the provided equation.
Step 1: Use the distributive property
Step 2: Subtract 6 from both sides.
Divide 2 from both the sides.
Now we need to find in which step Sarah use distributive property.
From the above calculation we can be concluded that Sarah use distributive property in Step 1.

Answer:
144 squared ft
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
Given the information:
- height - 3
- length - 11
- width - 4
- slant height - 5
As we know that, the ramp is a triangular Prism, so to find how much wood did it take to cover the ramp we need to find the total surface area of the triangular prism
1/ The area of the central rectangle
A = lw = 11*4 = 44 squared ft
2/ The area of the rectangle to the left
A = hw = 3*4 =12 squared ft
3/ The area of the rectangle to the right
A = slant height* length = 5*11 = 55 squared ft
4/ The area of the two triangles
A = 2 (1/2*h*l) = h*w = 3*11 = 33 squared ft
=> the total surface area of the ramp is: 44 + 12 + 55 + 33 = 144 squared ft
Hope it will find you well.
