Question

PLEASE HELP WITH ALGEBRA HOMEWORK :)))))

Answer 1

h = 20

Explanation:

A = 1/2h(B+b) , A = 150, B = 8, b = 7

lets rearrange the equation so we can solve for h

`(2A)/((B+b)) =h`

2(150) / (8+7) = h

300/15 = h

20 = h

Answer 2

`h=20`

Explanation:

`A = (1)/(2)h(B+b)`

`150=(1)/(2)h( 8+7)` (substitution)

`300=h(8+7)`

`15h=300`

`h=20`

Hope this helps :)
