Answer:

1. 12x - 24

2. 5a + 30b - 10c

Step-by-step explanation:

1. 3(4x - 8)

Distribute and multiply the 3 by each terms inside the parenthesis.

3(4x) = 12x

3(-8) = -24

12x - 24

2. 5(a + 6b - 2c)

Distribute and multiply the 5 by each terms inside the parenthesis.

5(a) = 5a

5(6b) = 30b

5(-2c) = -10c

5a + 30b - 10c
