The answer is D. You can cancel the (x+1) on the top and bottom because they are the same number. 

The expression that is equal to the rational expression when x does not equal to 5 or -1 is; (x - 7)/(x -5)

How to simplify Algebraic Expressions?

We want to simplify the algebraic expression;

(x - 7)(x + 1)/(x + 1)(x - 5)

Now, looking at the given expression, we see that (x + 1 ) is common to both numerator and denominator and as such they will cancel out to leave us with;

(x - 7)/(x -5)
