Answer
$-13x-21$
Work Step by Step
We start with the given expression: $-2(x-4)-5(x+7)-6(x-1)$
We use the distributive property: $-2x+8-5x-35-6x+6$
We use the commutative property to rearrange like terms: $-2x-5x-6x+8+6-35$
We use a form of the distributive property to combine like terms: $(-2-5-6)x+(8+6-35)$
We add and subtract inside the sets of parentheses: $-13x-21$
