Question

Emily wants to hang a painting in a gallery but the painting and frame must have an area of 31 square feet. The painting is 5 feet wide by 6 feet long. The frame must have an equal width of x on each side. Which quadratic equation represents the area of the painting and frame combined?

Answer 1

4x2 + 22x − 1 = 0

4x2 + 22x + 31 = 0

x2 + 11x − 1 = 0

x2 + 11x + 31 = 0
