20 and 1 Seems to be a common problem. Add the sum to the difference and divide by 2 gives one number. Then start over and subtract the smaller of the two givens from the larger and then divide by 2 to get the other number. So here you have (21+19)/2 and (21-19)/2

I think the question may refer to which two squares differ by 21. Two solutions : 112 - 102 = 121 - 100 = 21. 52 - 22 = 25 - 4 = 21.

The spacing between any two consecutive square numbers (n) and (n+1) is equal to (2n +1), so for 2n+1 =21, n =10 and the numbers are 121 and 100.However, there is a non-consecutive pair as well: 25 and 4.The squares lower than 100 are 1, 4, 9, 16, 25, 36, 49, 64, and 81, and an examination of these shows that there are no other pairs that satisfy the conditions.

For natural numbers, 5 times. For all real numbers, infinitely many times.

No

24 + 21 = 45 24 - 21 = 3 Therefore, the two numbers are 21 and 24.

The numbers are: 1 plus square root of 21 and 1 minus square root of 21

The two numbers are 21 and 7.

The numbers are: 3 +square root 21 and 3 -square root 21

Start by dividing 44 by 2 to get 22. Therefore, 22 + 22 = 44. If we subtract 1 from one number, and add 1 to the other number, the sum will be the same, but now using two consecutive odd numbers; ie, 21 + 23 = 44. Therefore, the smaller number is 21.

223 and 21 if you multiply them. 9366 and 2 if you divide them. 4600 and 83 if you add them. 4686 and 3 if you subtract them.

You need at least two numbers to find a GCF. The GCF of 21 and 42 is 21.
