Answer: the first one is C
the second one is B
The answer is 1/(x+4)
Explanation:
You would factor out the denominator
So,
(X-4)(x+4)=x^2-16
So, x-4/(x+4)(x-4)
Then x-4 cancels each other out from the numerator and denominator
Leaving 1/x+4
Plug in g equals -5 x -2 which equals 10 because 2 negatives are a positive then 10-6 equals 4
The anwser is 4
