Question

What would the phrase "twice the sum of a number and three" look like as a variable expression?

2+(2n+3)

2(2n−3)

2(n+3)

2n + 3

Answer 1

c?

Answer 2

yes it would be c

Answer 3

The sum is what two numbers add up to.
So the sum of a number and 3 would look like (any letter will work)
x + 3
The 'twice' will just make it multiplied by two :)
So 2(x + 3)
