9+ 4 (x + 2) - 3x what is the term that best describes 3 in this expression?

For this case we have that by definition, a coefficient is a factor linked to a monomial.

Example:

- : It's the sign

5: It is the coefficient

x: It is the variable

3: It is the degree

Then, according to the given expression, we can conclude that the number 3 that accompanies the variable "x" is defined as a coefficient.
