Front

What is the formula for the area of a rectangle if the length is 7 inches less than twice the width?

Back

A(w) = 2w^2 - 7w

Front

How do you solve for x in the equation y = 2x - 2?

Back

x = \frac{y + 2}{2}

Front

What inequality represents the goal of earning at least $500 from selling boxes of popcorn and pretzels?

Back
