Question

in the equation $9c = 18$, the 9 is called a (1 point)
product.
term.
variable.
coefficient.

Explanation:

A coefficient is a numerical factor multiplied by a variable in an algebraic term. In $9c$, $c$ is the variable, and 9 is the number multiplying it. A product is the result of multiplication, a term is a single part of an expression, and a variable is a symbol representing an unknown value, so none of these match 9's role here.

Answer:

D. coefficient.
