Use the distributive property to expand -4(-2/3+3x). Which is an equivalent expression?

Bad White [126]

$- 4 \times ( \frac{2}{3} + 3x)$
Multiply each term in the parentheses, namely 2/3 and 3x, by the only term outside of the parentheses, -4.

Each of the resulting products becomes a new term in the addition.

$( - 4 \times \frac{2}{3} ) + ( - 4 \times 3x)$
$( - \frac{8}{3} ) + ( - 12x)$
$- \frac{8}{3} - 12x$
You may choose to keep the answer this way, or continue to change the improper fraction into a proper fraction. A lot of teachers also prefer to have the highest degree terms (terms that have variables with the highest powers) on the left.

$- 12x - 2 \frac{2}{3}$
