Question

question 1 of 6
select the correct answer.
which of the following represents a coefficient from the expression given?
$9x - 20 + x^2$
options: $x^2$, 9, 20, $x$

Explanation:

Step1: Recall coefficient definition

A coefficient is a numerical factor of a term with a variable.

Step2: Analyze each option

• \(x^2\): It's a term with variable \(x\) (exponent 2), no numerical coefficient here (implicit 1, but not an option).
• \(9\): In the term \(9x\), 9 is the coefficient of \(x\).
• \(20\): It's a constant term, not a coefficient.
• \(x\): It's a variable, not a coefficient.

Answer:

9 (the option with "9")
