Any irrational number, when added to 13, will produce an irrational number.
To find the average, add up all the numbers and then divide the sum by the number of numbers you added. 7+11+21=39 39/3=13 The average is 13.
To find the least number that must be added to 165 to make it a perfect square, we first determine the nearest perfect squares. The perfect squares near 165 are (12^2 = 144) and (13^2 = 169). Since 165 is closer to 169, we calculate (169 - 165 = 4). Therefore, the least number that must be added to 165 to make it a perfect square is 4.
Any irrational number will do.

-13 is the number must you subtract from -13 to get a difference of 0

It is: 13+x+7x or as 13+8x
Any irrational number will do.

Average= All of your numbers added together divided by how many numbers you have. 13+17=30 30/2=15
Since the number is halved when reduced by 13, then the number must be twice 13 = 26.
