Which expression is equivalent to the algebraic expression below?

3 (-2x - 1)

a x - 1

b - 6x - 3

c x + 2

d - 6x - 1

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.

b) - 6x - 3

Step-by-step explanation:

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