***PLEASE HELP


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?

Image of a frame 6 feet wide by 7 feet long, with an of x on the bottom and right sides

4x2 + 26x + 45 = 0
4x2 + 26x - 3 = 0
x2 + 13x - 3 = 0
x2 + 13x + 45 = 0

Answer 1

\(\large{(6+x)(7+x)=45\\x^2+13x+42=45\\45-42=-3\\x^2+13x-3=0}\)

Answer 2

so the answer is C?
