Its a math question. Using distributive property.
what is the answer to -2(w+8)
all you have to do here is multiply by the -2
so, -2(w+8) would become (-2*w) + (-2*8) which equals
(-2w) + (-16) = -2w - 16
In the Distributive Property you obtain the answer by multiplying each component inside the bracket by the number outside the bracket and then adding together. For instance, 3(4+x) = 3*4 +3*x = 12+3x.
