We're trying to evaluate a fractional expression here:
The first thing to do, is factor everything we can. The quadratic factors to (x + 1)(x+5) and the expression above that factors to 3(x - 4). 2x + 2 factors to 2(x + 1).
It looks a little complicated now, but if we combine the two we can cancel some stuff.
Still looking complicated, but look, we have (x+1) and (x+4) on the top and the bottom, that means they don't matter and we can get rid of them:
Tada! The area is 6/(x+5). We'd need to know x to go any further!

Answer:
(x) =
Step-by-step explanation:
let y = g(x) and rearrange making x the subject
y = x - 9 ( add 9 to both sides )
y + 9 = x
Multiply both sides by 5 to clear the fraction
5y + 45 = 3x ( divide both sides by 3 )
= x
Change y back into terms of x, thus
(x) =
