Front

What is the distributive property in algebra?

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

Solve for n: -4(8 + 5n) = 8. What is n?

Back

n = -2

Front

What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

If the length of a rectangle is 12x and the width is 1, what is the area?

Back

Area = 12x - 2.

Front

Combine like terms: 3x + 2x + 3y - 7y. What is the result?

Back

5x - 4y.

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

Simplify the expression: -9(14p - 8) - 4p. What is the result?

Back

-130p + 72.

Front

What is a like term in algebra?

Back

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

Front

Simplify the expression: -6x + 4(-x - 3). What is the result?

Back

-10x - 12.

Front

What is the first step in solving an equation?

Back

The first step is to simplify both sides of the equation, which may include distributing and combining like terms.
