Question

Which algebraic expression represents the statement: the sum of twice a number and six.

2n-6

2n+6

n + 6

n - 6

Answer 1

Hey there!

The sum means that you are adding. That only leaves the answers B and C. It says twice a number, so this would be 2n because n is not known and would be a variable. The answer would be B. 2n+6.

I hope this helps!
