Katie wants to hang a painting in a gallery. the painting and frame must have an area of 45 square feet. the painting is 6 feet wide by 7 feet long. which quadratic equation can be used to determine the thickness of the frame, x? (5 points)

4x^2 + 26x + 45 = 0
4x^2 + 26x − 3 = 0
x^2 + 13x − 3 = 0
x^2 + 13x + 45 = 0
