32
Because
1 times 1=1 ,1plus1=2
2 times 2=4,4plus4=8
3 times 3=9,9plus9=18
4times4=16,16plus16=32
<span>437 = (21 + x)(21 - x), then x = 2, -2</span>
You have to use the formula cost over quantity
Divide 8 and $2.88
The answer is.
0.36
B. 10.1%
(2)(12)($88.18) ÷ [($1100)(18+1)]
(2,116.32) ÷ (20,900)
= 0.1012
= 10.1%
