No.
6 = 2*sqrt(x-5)
62 = (2*sqrt(x-5))2
36 = 4 * (x-5)
9 = x-5
x = 14

It just equals 5 * (sqrt(13)+3). Remember -- you only need to remove the radical from the denominator, not the numerator.

I'm not sure how you got 13-3, but it's incorrect.
Denominator = (sqrt(13)-3) * (sqrt(13)+3)
= (sqrt(13) * sqrt(13) + 3*sqrt(13) - 3*sqrt(13) - 9)
= 13 - 9 = 4
So the answer would be:
5/4*(sqrt(13) + 3)
(As an aside, and with all due respect, if you have any desire to continue your education in math or the sciences, or if you ever want to get serious about sports betting, I'd have to suggest taking some time to brush up on your elementary algebra.)
