Which statement about 4+2x is true
Leno4ka [110]

Answer:

4+2x is a sum.

Step-by-step explanation:

It can't be 1, because the coefficient of "x" is 2.

It can't be 2, because there aren't two variables in 4+2x. The only variable is x.

It can't be 4, because 4+2x is ADDING, not multiplying.

There we go!
