Question

Medal!
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 1

hi,
\[A = \frac{ 9 }{ 2 }(b + 35)\]
\[(b + 35 )= \frac{ 2A }{ 9 }\]
\[b = \frac{ 2A }{ 9 } -35\]

Yep!! that;s it and now I think ya can guess the answer!!!''

Hope this will help ya out!!!
