n(n+3)-4
2n+3n-4
If n is 0
2*0+3*0 -4
0+0-4
=4
if n is 1
2*1+3*1+-4
5-4=1
If n is 2
4+6-4

If n is 3

If n is 4

2^3 x 3^3 =216
Divisors of 216 are 1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 18 + 24 + 27 + 36 + 54 + 72 +108 + 216 = 600
so then i + j = 3 + 3 = 6

As Alan said if it is a multiple of 6 the has to be divisible by 2 and 3. now it is only divisible by 2. So only 2,4, or 8.
There are 3 possible values
As the guest said There is should be 4 ft of space when she parks her car. 4/2 = 2 ft so her wheels should be 2 ft away from the front of the garage
The difference is 5mph in 8 hours they will be 40 miles away (as Guest Said)
Well The 2 postcards can go into the mailboxes like this
(1,3) (2,1) (1,2) ( 2,3) ( 3,2) ( 3,1) (1,1) (2,2)(3,3)
5:9 and x:250 as aszun said you can convert to fractions to get 1250/19
6. 3 possible digits, 2 digit numbers 2*3=6 also the 2 digit numbers are 24,27,72,74,72,42
it is a real number and a rational number
