Question

henley needs to calculate the base of a trapezoid, b, given the area, a, in inches. She need to rearrange the formula a=16(b+4). Solve the formula for b in terms of a​

Answer 1

b = a/16 - 4.

Explanation:

a=16(b+4)

b+4 = a/16

b = a/16 - 4.

Answer 2

b = (a/16) - 4

Explanation:

a = 16(b + 4)

a = 16b + 64

16b + 64 = a

16b = a - 64

16b/16 = (a/16) - 64/16

b = (a/16) - 4
