Question

select the correct answer.
which of the following represents a constant from the expression given?
$15x^2 + 2x + 9$
a. 15
b. 2
c. 9
d. 24

Explanation:

Step1: Define a constant

A constant is a term in an algebraic expression that has a fixed value and does not contain a variable.

Step2: Analyze each option

• Option A: 15 is the coefficient of \(x^{2}\), so it is not a constant.
• Option B: 2 is the coefficient of \(x\), so it is not a constant.
• Option C: 9 is a term without a variable, so it is a constant.
• Option D: 24 is not present in the expression \(15x^{2}+2x + 9\).

Answer:

C. 9
