Greetings!

"Use the distributive property for $-8 (x / 3)$ ."

The distribute property is used to simplify an expression/equation. This is done by multiplying the contents of the parenthesis by the number outside of bracket.

 $-8 (x / 3)$
$=(-8*x / -8*3)$
Simplify.
 $=(-8x/-24)$

Hope this helps.
