Girls : boys = 1:1 girls who sing : girls who do not sing = 1:2
8 girls sing in the show.
How many students are in the show altogether?

48 students

Step-by-step explanation:

Girls who sing : girls who don't sing = 1 : 2

Let total number of girl be x

Part of girls who sing = (1/3)x

Part of girls who sing = 8

                             x = 24

Number of girls = 24

Girls : boys = 1 : 1

Number of boys = number of girls

Total students in the show = 24 + 24 = 48

(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

i those same problems in math and dont know how to do them
