$5 x + 20$

#### Explanation:

Multiply everything inside the brackets by the 5 that is outside of them. So we have

color(green)(color(red)(5)(4+x)" "->" "color(red)(5)xx4" "+" "color(red)(5)xx x

$\text{ "20" "+" } 5 x$

Or you may if you wish write it as:

$5 x + 20$

$5 \left(4 + x\right)$

$5 \cdot 4 + 5 \cdot x =$

$20 + 5 x$
