There are two solution: -3 and +2.
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.

A normal 3x3 magic square has a sum of 15. So you subtract 3 from each number in the square.
To calculate 4 times the sum of a number and 6, you would first find the sum of the number and 6, then multiply that sum by 4. Let's represent the number as 'x'. So, the sum of the number and 6 would be x + 6. Multiplying this sum by 4 gives you the expression 4(x + 6), which simplifies to 4x + 24.

The sum of three times a number and its square is 10 more than 6 times a number?
To find "six less than the square of the sum of 5 and a number," we first express the number as ( x ). The sum of 5 and ( x ) is ( 5 + x ). Squaring this sum gives us ( (5 + x)^2 ). Finally, subtracting 6 results in the expression ( (5 + x)^2 - 6 ).
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.

A normal 3x3 magic square has a sum of 15. So you subtract 3 from each number in the square.
To square a number, multiply the number by itself.Example: The square of 6 is (6 times 6) = 36.Note: This gives you the area only if the figure is a square.
To calculate 4 times the sum of a number and 6, you would first find the sum of the number and 6, then multiply that sum by 4. Let's represent the number as 'x'. So, the sum of the number and 6 would be x + 6. Multiplying this sum by 4 gives you the expression 4(x + 6), which simplifies to 4x + 24.
Oh, dude, the sum of the square of 6 and 8 is 36 + 64, which equals 100. So, like, if you square 6, you get 36, and if you square 8, you get 64. Add them together, and boom, you've got 100. Easy peasy lemon squeezy.
