$13 + 2 h$

#### Explanation:

SUM in maths is the answer to an addition.
It is always used with the word AND to show which values are added together.

$\text{The number}$ is already defined as ' h '.

"Twice" means times by 2.

So, 13 and twice 'h' are being added together.

$13 + 2 h$

[Note that the following means something different:

"Twice the sum of 13 and h"

Here 13 and h are to be added, and the answer is doubled.

$2 \left(13 + h\right)$]
