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

the answe ris B

Same length is comparing because it’s saying its the same and not different
