A man is trying to zombie-proof his house he wants to cut a length of wood that will brace a door against a wall. the wall is 4 feet away from the door and he wants to brace to rest to feet The door. about how long should you cut the brace? If he needs to buy the word for the brace how much will it cost if a foot of wood cost $3.25 if he pays with a $20 bill how much change will he get? (show all work)

(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

could you provide figure.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
