Let x equal the number of books bought.
45 = 3x - 6
(This is the answer because $45 is the total price, each book is $3, and $6 is discounted from the actual price.)
Answer:
121 sq. in
Step-by-step Explanation
area of the frame = 48 square inches
if is the side length of the square, then ( + 2) is the side length of the square after the frame has been added.
the area of the picture + the frame is:
( + 2) ( + 2)
the area of just the frame is given by ( + 2) ( + 2) - x :
( + 2) ( + 2) - x =48
²+ x 2 + 2 x + 2 x 2-² = 48
² + 2 + 2 + 4-² = 48
4 + 4 = 48
then subtract 4 from both sides:
4x = 44
and divide both sides by 4:
x = 11
the area of the square is 11 (11) = 121.
i think this is correct?
