During one week, the price of a stock decreased $4 per day for 3 days and increased $2 per day for 4 days. which integer represents the change in the price of the stock over the week?
–20
–4
4
20

-4

Step-by-step explanation:

Given:- During one week,

The price of a stock decreased $4 per day for 3 days and increased $2 per day for 4 days.

⇒Decreased price=3 times ($4)=3×$4=$12

Increased price=4 times $2=4×$2=$8

Change in price= Increased price - decreased price

=$8-$12

=$(8-12)

=$(-4)

=-$4

Therefore, Change in price of the stock over the week represents by integer -4.

(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

answer: 2 and 1
