5. a piece of plywood has a length that is 5 more than twice its width. write the expression that represents the area of the plywood.

5w^2 = A
 
You would multiply the width (w) by 5 because it's 5 times more than twice it's width. Then w (Width) would be to the power of 2 because it's 5 times more than twice its width. And this will all equal the Area (a) 

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
