The sum of 32 is 9.
11 + 12 + 9 = 32
sum of 14th square number and 10th square number
square of 5=5*5=25 Now sum of 23 and square of 5=23+25=48 Now one third of sum of 23 and square of 5=48/3 =16 Hence 16 is answer
122
36 is a perfect square number.
the answer is 34
There are two solution: -3 and +2.
The sum of two number times a third numberis equal to the sum of each addend times the third number
That's the distributive property.
They don't necesarily,3 is a triangular number and 10 is a triangular number. Their sum is 13 which is not a square number.They don't necesarily,3 is a triangular number and 10 is a triangular number.

Sum = Sum + first number Sum = Sum + second number Sum = Sum + third number Average = 1/3 x Sum
Let 'N' be the number. The sum of the number and 13 is (N+13).The square of the sum of the number and 13 is (N+13)2N2 + 26 N + 169.It's probably easier to add 13 to the number and then square that answer ... less arithmetic.
