Teds science class collects aluminum cans to sell to the recycling center. the center pays a fixed amount for each kilogram of aluminum. write a formula that will ted determine how much money his group will recieve for the cans. let t= total amount, n=number of kilograms of cans, a= amount the center pays per kilogram

(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

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.
