Step-by-step explanation:

find the area of one of the squares (l*w) and then multiply it by four. find the area of one of the triangles (.5b*h) and then multiply it by four. add up the two numbers for the surface area

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20
