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?


b = 2A over 9 + 35


b = 2 multiplied by A over 9 - 35


b = 2 multiplied by A plus 35, all over 9


b = 2 multiplied by A minus 35, all over 9

Answer:

b

Step-by-step explanation:

b - the other base;

A = 9/2 ( b + 35 )   / * 2  ( we will multiply both sides of the equation by 2 )

2 A = 9 ( b + 35 )

b + 35 = 2 A / 9 

b + 35 - 35 = 2 A / 9 - 35

b = (2 A / 9 ) - 35
