Question

Which expression is equivalent to 2 + 3n + 2 + 9n?

A) 16n
B) 3n + 8
C) 4(3n + 1)
D) 4(3n + 4)

Answer 1

The expression 2 + 3n + 2 + 9n is equivalent to 12n + 4. Hence, C) is correct.

Step-by-step explanation:

The expression 2 + 3n + 2 + 9n is equivalent to 12n + 4. To simplify the expression, combine like terms by adding the coefficients of the 'n' terms together. So, 3n + 9n equals 12n.

The constants 2 and 2 can also be added together to get 4. Therefore, the expression is equivalent to 12n + 4.
