Alexei wants to hang a mirror in his boat, and put a frame around it. The mirror and frame must have an area of 19.25 square fee t. The mirror is 3 feet wide and 5 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?
1 answer:
<span>The first part is already in squared terms. "19.25 sq ft"
Taking the measurements for the mirror 3ft and 5ft, you'd get: "15 sq ft."
Subtract that answer from the previous number to get "4.25 sq ft.
