What is the value of k? 11= −3k − 22 − 8k can somebody me plz?

k=-3 I'm glad to help!

(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

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
