Answer:

single term
sum of 4 terms, some of which can be expanded further

Step-by-step explanation:

1. 3x

This is a single term with one variable of the first degree.

2. 4x + 9(2x + 1) x² + 6(-2x + 1) - 3(7 + x?)

This is a sum of 4 terms, some of which can be expanded:

4x
9(2x+1)x^2 ⇒ 18x^3 +9x^2
6(-2x +1) ⇒ -12x +6
-3(7+x?) ⇒ -3x? -21

The expression can be simplified by combining like terms.
