Question

select the correct answer.
consider the expression below.
$9 + 4(x + 2) - 3x$
select the term that best describes \3\ in the given expression.
a. constant
b. variable
c. coefficient
d. exponent

Explanation:

Step1: Recall definitions

  • Constant: A fixed number.
  • Variable: A symbol (usually letter) representing unknown value.
  • Coefficient: A number multiplied by a variable.
  • Exponent: A number showing how many times a base is multiplied by itself.

Step2: Analyze "3" in \(9 + 4(x + 2) - 3x\)

In the term \(-3x\), "3" is multiplied by the variable \(x\). So it fits the definition of a coefficient.

Answer:

C. coefficient
