Translate to an equation:
x + x2 = 30
Solve for x:
x2 + x - 30 = 0
(x + 6)(x - 5) = 0
x = 5, -6

The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.
The numbers are 21 and 63.
Well, honey, if the sum of 4 numbers is 83095 and two of them are 29854 and 17031, then the sum of those two is 46885. Subtract that from 83095 and you get 36210. Since the third and fourth numbers are the same, divide that by 2 and you get 18105. So, the third number is 18105.
example for sum of rational numbers is 1/3 + 1/5 Example for sum of irrationals is Pi + e where e is is base of natural log Another is square root of 2 + square root of 3.
The formula for finding the nth square number is n^2. Therefore, the 3rd square number is 3^2 = 9, and the 6th square number is 6^2 = 36. To find the sum of the 3rd and 6th square numbers, you add them together: 9 + 36 = 45. So, the sum of the 3rd and 6th square numbers is 45.

There aren't any whole numbers that satisfy this.
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.

The number is 7.
The average of a group of numbers is equal to the sum of the numbers divided by the number of numbers. If you want to find the sum of the five numbers, just multiply 790.6 by 5 to get the sum, which is 3953
