(3 + x)2 = 16
Square rooting both sides gives 3 + x = 4
x = 4 - 3
x = 1
The number is 1.

25 is the sum of 9 and 16. (52 = 32 + 42)
Yes 16+9=25
The number is 3 less than the square root of 16 ie 3 less than 4, so it's 1.
25 is a square number, and the sum of 9 and 16 is 25. 9 and 16 are also square numbers.
The number is 1.
4*4=16 sum of 1+6 is 7, difference is 5 so 16 is answer

16
Yes 16+9=25
The number is 3 less than the square root of 16 ie 3 less than 4, so it's 1.
The question cannot be answered because it is ambiguous. Does "twice the sum of 16 and a number" mean "2*16 + x" or does it mean "2*(16 + x)"
16

If you have a data set, simply take the square root of the sum of the squares of the data points. Let's say you have three numbers a, b, and c. RSS = SQRT(a2 + b2 + c2).
