It can be if the first number is x + 21 and the second is x for any number x.
112 - 102 = 21
39
They are: 25-4 = 21
The inverse operation of adding 21 is subtracting 21. This means that if you subtract 21 from a number, and then add 21 to the result, you will get back to the original number.
25 and 4 or 121 and 100
100 - 21 = 79
The number is 21.
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 smaller number is 8, and the larger one is 21. 8 + 13 = 21 8 + 21(2) = 50
160 - 21% = 126.4
14. If you have the numbers in order like so: 7,9,11,14,21 you can see that 21 is the greater number. You then subtract 21 from the smallest number, 7, and you get 14.
