Distributive Property and Combine Like Terms (Per. 3)

Front

What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of terms that have the same variable raised to the same power.

Front

What is a variable in mathematics?

Back

A variable is a letter that represents a number in an expression or equation.

Front

What is a coefficient?

A coefficient is a numerical factor in a term of an algebraic expression, indicating how many times the variable is multiplied.

Front

What is a constant in an expression?

Back

A constant is a fixed value that does not change, represented by a number without a variable.

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated by adding the lengths of all four sides, or using the formula P = 2(length + width).

Front

How do you find the perimeter of a triangle?

Back

To find the perimeter of a triangle, add the lengths of all three sides together.

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to reduce it to its simplest form by combining like terms and performing any operations.

Front

What is the expression for the perimeter of a rectangle with length x and width y?

Back

The expression for the perimeter is P = 2x + 2y.

Front

What is the expression for the perimeter of a triangle with sides x, y, and z?

Back

The expression for the perimeter is P = x + y + z.
