Answer:
s+7 is numerator of the given expression.
Explanation:
We have bee given a rational expression:
is the general representation of the Rational expression where, p is numerator and q is denominator.
So, our given expression is:

We will take the LCM so, given expression can be rewritten as:
(1)
Comparing (1) with general rational expression written above
p=s+7 which is numerator of the given expression.
