Answer:

Step-by-step explanation

u will use the distributive property...that means multiply the number outside the parenthesis by everything in the parenthesis to get rid of the parenthesis.

I will write this out step by step...

12(-1.4m + 0.4) =

12(-1.4m) + 12(0.4) =

-16.8m + 4.8 <=== thats all u can do because u cant add unlike terms...if that 4.8 had an m with it, then u could add them.

Answer:

- 16.8m + 4.8

Step-by-step explanation:

12 (–1.4m + 0.4) =

the number before the parentheses is multiplied by the numbers in the parentheses

  1. 12 * (-1.4m) = -16.8m
  2. 12 * 0.4 = 4.8

  1. ..
  • the number is multiplied by the numeric part

12 * 1.4m = (12 * 1.4)m = (16.8)m = 16.8m

  • - * - = +
  • + * + = +
  • - * + = -
  • + * - = -

so +12 * (-1.4m) = -16.8m

in the end, the answer is -16.8m+4.8
