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
