Answer:
C
Step-by-step explanation:
First, to make things simpler, let's create a common denominator for every term. We can do this by multiplying (x+4) and (x+3) when the denominator has a (x+3) or (x+4), respectively. In other words:
Now that they all have a common denominator, we can combine them:
Now, divide them. Recall how to divide fractions. You "flip" the second term and change the division sign into a multiplication sign.
Notice the denominator of the first term and the numerator of the second; we can cancel them out.
Now, we just need to simplify.
