Question

equivalent
not equivalent

Explanation:

Step1: Expand the second expression

Use distributive property: $a(b+c)=ab+ac$
$2(3 + n) = 2\times3 + 2\times n = 6 + 2n$

Step2: Compare the two expressions

Rearrange terms of the expanded expression: $6 + 2n = 2n + 6$, which matches the first expression.

Answer:

equivalent
