Which of the following is equivalent to the equation - 5 (3x - 8) = - 45?

A. - 15x - 40=-45

B. - 15x + 40 = - 45

C. - 15x - 8 = - 45

D. 15x + 8 = - 45

Distributive property is

a (b+c) = ab+ac so

first, distribute

remember than (-) times (-) = (+)

-5 (3x-8) = (-5) (3x) + (-5) (-8) = - 15x + (+40) = - 15x+40

so it is - 15x+40=-45
