Alisa is making a design for the bottom of a dress using trapezoid shapes cut from different colors of fabric. Each trapezoid has base lengths 5 inches and 10 inches and a height of 6 inches. How much fabric does she need for 4 trapezoids?

b. x + 1

step-by-step explanation:

i'am smart

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
