Answer:
6a-12b+8
Step-by-step explanation:
Im pretty sure this is the answer but if it's not im so sorry
Lets say she cuts squares of x by x in length.
Area of bottom will be (20 - 2x)(11 - 2x) = 80 inches squared
220 - 40x - 22x + 4x^2 = 80
4x^2 - 62x + 140 = 0
x^2 - 15.5x + 35 = 0
Using quadratic equation;
you get x = 2.743753901 0r 12.7562461 inches
The length of the square cannot be more than 11 inches
So the only squares you can cut are:
2.743753901 inches by 2.743753901 inches squares.
Yes, it would be about 61%.
65 - 17 = 48 books delivered
as 8 per box , 48/8 = 6 boxes delivered
now she has97 books, 97- 17 = 80
as 8 per box, 80/8 = 10 boxes in total,
