the length, width, and height of a rectangular prism can be represented by the expressions (x + 3), (x + 7) and (x— 1). Write an expression to represent the surface area of the prism.

answer: the answer is 23

step-by-step explanation:

(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

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
