Question

[9.06] Tabitha wants to hang a painting in a gallery but the painting and frame must have an area of 58 square feet. The painting is 7 feet wide by 8 feet long. The frame must have an equal width of x on each side. Which quadratic equation represents the area of the painting and frame combined?



x2 + 15x − 2 = 0

x2 + 15x + 58 = 0

4x2 + 30x − 2 = 0

4x2 + 30x + 58 = 0

Answer 1

option a

Answer 2

how??? @ash2007ray

Answer 3

frame width=x
NOW NEW LENGHT=7+x
new width=8+x
area=length*width=(7+x)*(8+x)
now this should be = 58
(7+x)*(8+x)=58
now expand it
get the answer!!!
