Five multiplyed by the sum of three and a number:

$5(3+n)$

The sum of one and the number:

$1+n$

Sum of the two quantities:

$5(3+n)+1+n$

To simplify:

- Use distributive property to remove parentheses:

$\begin{gathered} \text{Distributive property:} \\ a(b+c)=ab+ac \\ \\ =15+5n+1+n \end{gathered}$

-Combine like terms:

$=16+6n$
