PreAlg Lesson 3-1 Identify & Combine Like Terms

Front

What is a constant in an algebraic expression?

Back

A constant is a fixed value that does not change. In the expression x - 53 - 4x - w + 6x + 8, -53 is a constant.

Front

What does it mean to combine like terms?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power.

Front

What are like terms?

Back

Like terms are terms that have the same variable and exponent. For example, 3x and 5x are like terms.

Front

Identify the like terms in the expression: x - 53 - 4x - w + 6x + 8.

Back

The like terms are x, -4x, and 6x.

Front

What is the simplified expression for x - 53 - 4x - w + 6x + 8?

Back

The simplified expression is 3x - w - 45.

Front

What is a term in an algebraic expression?

Back

A term is a single mathematical expression that can be a number, a variable, or a combination of both, such as 4x or -53.

Front

In the expression 2w - 3x + 9 + 6w - 2x - 10, what are the like terms?

Back

The like terms are 2w and 6w, and -3x and -2x.

Front

What is the perimeter of a rectangle represented by the expression 2w - 3x + 9 + 6w - 2x - 10?

Back

The simplified expression for the perimeter is 16w - 10x - 2.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor that multiplies a variable. In -4x, -4 is the coefficient.

Front

List the terms in the expression x - 53 - 4x - w + 6x + 8.

Back

The terms are x, -53, -4x, -w, 6x, and 8.
