Question

What is the constant in this algebraic expression 5a+2?

Answer 1

The constant is `2`. See explanation.

Explanation:

A constant is a term in expression which contains only a number (positive, or negative) without any variables (letters). Here an expression is a sum of 2 smaller expressions. The term `5a` contains a variable `a`, so it is not a constant.

The term `2` does not contain any letters, so it is a constant.
