Answer: 14x+4

Step-by-step explanation:

3(2+4x)+2x-2

simplify

Distribute: 6+12x+2x-2

Add like terms: 14x+4

Answer:

3C + D = 14x + 4

Step-by-step explanation:

given

C = 2 + 4x and D = 2x - 2

Then

3C + D

= 3(2 + 4x) + 2x - 2 ← distribute parenthesis by 3

= 6 + 12x + 2x - 2 ← collect like terms

= (12x + 2x) + (6 - 2)

= 14x + 4
