Answer
$H$
Work Step by Step
The phrase "two times" means to multiply $2$ with another value.
The phrase "the sum of $a$ and $b$" means that we add $a$ and $b$ together.
So this exercise asks us to add $a$ and $b$ together and then multiply this value with $2$:
$2(a + b)$
This corresponds with answer option $H$.
