Emily wants to hang a painting in a gallery. The painting and frame must have an area of 31 square feet. The painting is 5 feet wide by 6 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?


4x2 + 22x − 1 = 0

4x2 + 22x + 31 = 0

x2 + 11x − 1 = 0

x2 + 11x + 31 = 0

The correct answer is 4x2 + 22x − 1 = 0  


That's what you get when you (5 + 2x)(6 + 2x) = 31


And you get to expand that based on the data that is already provided in the question.
