Question

Name the property of real numbers illustrated by the equation.

-3(x+4)=-3x-12

A: Distributive property
B: Associative property of addition
C: Associative property of multiplication
D: Commutative property of addition

Answer 1

Answer: Choice A) Distributive property

We're multiplying the outer -3 with the inner x to get -3x
Also, multiply the outer -3 with the inner +4 to get -12

So that's why -3(x+4) = -3x-12
