We can by simplifying the first expression:
[tex] \frac{(x+3)(x+8)}{5(x+8)} = \frac{x+3}{5}[/tex]
I will asume that second exressin is [tex]\frac{(x+3)}{5}[/tex]. Then the answer would be all number, because those two expressions are identical.
If we look at the expression you wrote in the question [tex]x+3/5[/tex], you can see that there are no numbers for which these two would be equal.
So the final answer is C.
