this was a question I found on the princeton review book for the SAT. I didn't understand their explanation so can you please explain it to me. Thankyou!!!
where it says square root, it is the square root of the whole g(a/2). (it does not include the 6)
where it says square root, it is the square root of the whole g(a/2). (it does not include the 6)

Then g(a/2) must be 36. First find what x makes g(x) = 36 by solving 5x + 2 = 36.
That's a/2. So a is double that value of x.
That's a/2. So a is double that value of x.

√5(a/2)+2. = 6
5a/2 = 36
5a = 72
a = 72/5
a =14.4
