Question

Is 3n+6 equivalent to 3(n+6)

Answer 1

Lets find out...
3(n + 6).....distribute the 3 through the parenthesis
3n + 18.....and this DOES NOT equal 3n + 6...so it is not equivalent

Answer 2

No. You must distribute the 3 to the n and 6 on the second formula.

3n+6 and 3n+18 is not equivalent.
