When the queen counted her jewels, she found that she had five pearls for each diamond, two opals and three rubies for each diamond, and two emeralds for each opal. if she has three diamonds, how many jewels does she have altogether?

I believe she would have 45 gems total

3 diamonds

5 pearls per diamond = 15 pearls

2 opals and 3 rubies per diamond= 6 opals and 9 rubies

2 emeralds per opal= 12 emeralds

3+15+6+9+12= 45 gems total

(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

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
