Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable in an algebraic expression.

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change and does not have a variable attached to it.

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power.

Front

Are 5x and 5y like terms?

Back

No, because they have different variables.

Front
