The equation below shows the area of a trapezoid, A, with a height of 9 cm, and one base 35 cm. : A = 9 over 2(b + 35) Which of the following formulas correctly solves for the other base, b? a. b = 2A over 9 + 35 b. b = 2 multiplied by A over 9 - 35 c. b = 2 multiplied by A plus 35, all over 9 d. b = 2 multiplied by A minus 35, all over 9

First step is to get "b+35" by itself. You can do so by multiplying the inverse of the fraction 9/2 on both sides.

Correct. So \[\large \bf \frac{2A}{9}~=~b+35\] To get the b alone we subtract the 35 over
