If 25% is 45 students, then 100% is 180 students. There are 180 students in the entire 7th grade class.

We can find the answer by replacing every occurrence of x with 9 in the given expression as shown below.

$\frac{ x^{2} +6}{x-6} \\ \\ 
= \frac{9^{2}+6 }{9-6} \\ \\ 
= \frac{81+6}{3} \\ \\ 
= \frac{87}{3} \\ \\ 
=29$

So, the value of expression at x=9 is 29
