Answer 2

Answer:

12x - 84y + 24z

Step-by-step explanation:

When doing these if there is a number outside of the parenthesis then that mean you have to combine those terms by that i mean

12(x -7y + 2z)

12× X is combined to be 12x

12 × -7y = -84y

12 × 2z = 24z

so your new expression would be

12x - 84y + 24z
