A machine produced 4,650 bottles of seltzer and put them in packs of six bottles. How many 6-packs did the machine make?

775

Step-by-step explanation:

Just divided 4,650 by 6 and you get 775.

There will be 775 packs.

Step-by-step explanation:

4,650 divided by 6=775. (I hope this helps:D)

(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
