All you do is add them so it it would be 6

The number is 4 (4+3) * (4+3) = 49 (4+2) * (4+2) = 36 49 - 36 = 13
[(x+3)^2] - [(x+2)^2] = 13 ==> 2x = 8 ==> x = 4. the number is 4!
A sum of 4 is more likely. Out of the 36 possible outcomes with a pair of 6-sided dice, only one will have a sum of 2 {1-1}. Three of the possibilities sum to 4. {1-3, 2-2, 3-1}
(x + 3)2 = (x + 2)2 + 9 x2 + 6x + 9 = x2 + 4x + 4 + 9 2x = 4 x = 2
the sum is example 2+2=4, 4 is the sum
If you mean: (x+3)^2 = (x+2)^2 +13 Then the value of the number x works out as 4
13 more than -4 = 9
5,6,2,3,9 has a greater sum than 10,4,5,1 and 2 which has a sum of 22.
