Find the value of x
X/5 + 1 = 5 X= ?

x = 20

Step-by-step explanation:

isolate the by subtracting 1 from both sides

then isolate the x by multiplying both sides by 5

so

hope this helps :))

(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
