Tabitha wants to hang a painting in a gallery. The painting and frame must have an area of 58 square feet. The painting is 7 feet wide by 8 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?
Image of a frame 7 feet wide by 8 feet long, with an of x on the bottom and right sides
x2 + 15x − 2 = 0
x2 + 15x + 58 = 0
4x2 + 30x − 2 = 0
4x2 + 30x + 58 = 0

Best ResponseYou've already chosen the best response.1so if a = 2 and b = 40, we can plug them into \[\Large h = \frac{b}{2a}\] what is the value of h when you do this?

Best ResponseYou've already chosen the best response.1what we do next is plug that value (10) in for x \[\Large y =2x^2 + 40x + 600\] \[\Large y =2(10)^2 + 40(10) + 600\] \[\Large y = ???\]
