Question

Step-by-step answer?

Answer 1

12x - 15

Explanation:

What you need to do for this is -3 · -4x + -3 · 5 = 12x+(-15). Which simplifies to 12x - 15.

Answer 2

hi

a ( b +c) = a*b +a*c

here a = -3

b = -4x

c = +5

so :

-3 ( -4x +5) = -3*-4x + -3* 5

= -12x + (-15)

= -12x -15

as I cannot add -12x and -15 ( they are two differents sort of figures )

so it's done
