It would have to be D: increasing the given orientation angle of the disk, but not exceeding and angle or90!
        
             
        
        
        
is the equation in the question written like the one in the bottom? Because for me to help you I must confirm what the equation looks like.

<span>log(x-3)+log(x) = 2 + log(x+2) 
---------------------------
log[(x-3)x] - log(x+2) = 2
-----
log[(x^2-3x)/(x+2)] = 2
----
(x^2-3x)/(x+2) = 2^2
-------
x^2-3x = 4x+8
x^2 - 7x - 8 = 0
Factor:
(x-8)(x+1) = 0
Positive solution:
x = 8</span>
        
             
        
        
        

Domain restrictions are what x values make the denominator zero. 
a² + 5a - 36 = (a + 9)(a - 4) 
a ≠ -9 ; a ≠ 4
