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

    so 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?

    h=-40/2(-2) h=10

    what we do next is plug that value (10) in for x \[\Large y =-2x^2 + 40x + 600\] \[\Large y =-2(10)^2 + 40(10) + 600\] \[\Large y = ???\]

    h = 10 and k = 800 making the vertex to be (10,800)

    in general, the vertex is (h,k)
