Answer 2

Sarah wants to hang a mirror in her room but the mirror and frame must not have an area larger than 15 square feet. The mirror is 3 feet wide and 4 feet long. Which quadratic equation represents the area of the mirror and frame combined? (The frame must have equal width of x on each side.)

Answer 3

ok, so the area of the whole thing is going to be height * width right? What is going to be the total length of your frame?

Answer 4

Add 2x to both 3 and 4..

it becomes:

(2x + 3) and (2x + 4)

Now this is your length and width..

Apply the formula for Area here:

\[\large Area = Length \times Width\]

Answer 5

how do i do that ?

Answer 6

\[Area = (2x+3)(2x+4) = 4x^2 + 7x + 12\]
