#### Answer

"A number term is also called a constant." The answer is "constant".

#### Work Step by Step

The answer to problem #5 is: "A number term is also called a constant." So, the answer is "constant."
If a polynomial contains a term that is merely a number, it is known as a constant.
Example: $x^{2} + 4x + 3$
There are three terms in this example.
Term #1: $x^{2}$
Term #2: $4x$
Term #3: $3$
The 3rd term in this example is only a number, $3$, which marks it as a "constant." In other words, it can't be modified by any other variable.
