Answer:
l(l - 2) = 168
Step-by-step explanation:
Let w = width
Let l = length
Let A = area
w = l - 2
A = l * w
also, A = 168
equating the two values of A
l * w = 168
l * (l - 2) = 168
l^2 - 2l = 168
l(l - 2) = 168
5/45, 6/54, 7/63
Any 2 numbers that you divide and have the ratio 1:9
1) $65 ÷ $6.50 = $10
2) Check Work: $10 × $6.50 = $65
$10 is your missing factor :)

For the answer to the question above, it is -18% because to find rate we subtract the rate, in this case, is .82 or 82% - 1 or 100% and that would give you the rate, in this case, its decreasing by an 18%
I hope my answer helped you.
