Arectangular picture frame has outside dimensions of 8 inches wide and 10 inches tall. if the glass on the picture frame has an area of 48 square inches. how wide is the width of the picture frame if the frame is the same width all the way around the picture?

1 inch

Step-by-step explanation:

If we call the thickness of the frame x, then the dimensions of the glass are:

w = 8 − 2x

h = 10 − 2x

The area of the glass is width times height:

48 = (8 − 2x) (10 − 2x)

Distribute and simplify:

48 = 80 − 16x − 20x + 4x²

0 = 4x² − 36x + 32

0 = x² − 9x + 8

Factor and solve:

0 = (x − 1) (x − 8)

x = 1 or x = 8

x can't be more than 4 (half the width of the frame), so x = 1 inch.

215.92 dollars is the answer
