Write the expression with only positive exponents and evaluate if possible. Assume all variables represent nonzero real
numbers.
-$$\frac { 4 } { 5 } ( - 5 y + 15 x - 5 z )$$
A) $- 4 y - 12 x - 4 z$
B) $- 4 y - 12 x + 4 z$
C) $- 4 y + 12 x + 4 z$
D) $- 4 y + 12 x - 4 z$

Distributing $\frac{4}{5}$ across each term in the parentheses gives: $\frac{4}{5}(-5y) + \frac{4}{5}(15x) - \frac{4}{5}(5z) = -4y + 12x - 4z$.
