Given the expression:
[tex]\frac{5}{x+3}+\frac{3x}{x+3}[/tex]Let's simplify the expression.
Since they have the same denominators, combine the expressions and add the numerators.
We have:
[tex]\begin{gathered} \frac{5+3x}{x+3} \\ \\ =\frac{3x+5}{x+3} \end{gathered}[/tex]Therefore, the simplified expression is:
[tex]\frac{3x+5}{x+3}[/tex]ANSWER: C
[tex]\frac{3x+5}{x+3}[/tex]
