John and Melanie are designing a science experiment for the school science fair. Their experiment requires a large amount of copper wire. They need 22 spools of copper wire that each contains 31 meters of wire. How many kilometers of wire do John and Melanie need for their experiment? Round your answer to the nearest tenth of kilometers. (Hint: 1 kilometer = 1000 meter)

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

the answer

b. they are parallel and will never intersect.
