Answer:

B

Explanation:

x/(x+3) + 3/(x+3) + 2/(x+3)

The denominator is the same for all, so you can simply add them all respectively...

(x+3+2)/(x+3)

Now combine the like terms...

(x+5)/(x+3)

X/(x+3) + 3/(x+3) + 2/(x+3)

Because the denominator is the same for all of them, (x+3), you can simply add all the numerators (top numbers) and put them on top of the common denominator. So it would be:

(X+3+2)/(x+3)

Combine like terms:

(X+5)/(x+3)

So your answer is B

I hope this Helps!
