He would have to make 10 visits at the ($12 per month + $4 each visit) gym to make the ($50 per month for unlimited visits) gym the cheapest option.

Explanation:

12 + (4 x 10) =

12 + (40) = $52

He would have to use it more than 10 times in the month.

Step-by-step explanation:

4x+12>50

4x=38

x> 9.5

4(10)+12>50

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
