Which expression is equivalent to the algebraic expression below?

3(–2x – 1)
a x – 1
b –6x – 3
c x + 2
d –6x – 1

Answer 1

b) -6x - 3

Explanation:

3(-2x-1)=3*(-2x)+3*(-1)= -6x - 3

Answer 2

B. -6x - 3

Distribute the 3, or multiply it by everything in the parentheses.

You multiply 3 times -2x to get -6x, and you multiply 3 times -1 to get -3.

Put these together to get -6x-3.
