I think it would be something like this: x-80 = (x*2)+12
        
             
        
        
        
Answer:

Step-by-step explanation:
Theorem: In the right triangle the leg is the geometric mean of the hypotenuse and the segment of the hypotenuse adjacent to the leg.
Based on the theorem above,

 
        
             
        
        
        
Volume of a cylinder is h x r^2 x pi
You have the volume and radius of each one, so taking 188.4=(2)^2 x 3.14 x h1, you can solve this equation for the height h1. Likewise, for the other graduated cylinder you take 314=2^2 x 3.14 x h2, and then solve for h2.
To get the difference in heights, just take h2-h1 after solving the equations for h2 and h1

All you have to do to solve this question is to plug in gx as any other number you would plug in to the f(x) to solve the equation. 
So it would be 
F(3x-8) = 3(3x-8)^2 - 5(3x-8) - 9 
Then FOIL the terms in the binomial or the first term, then after expanding the first term, distribute the numbers into each term inside the bracket and then at the end gather like terms to simplify.
