The variance.
Area is notated as Unit squared because you are only dealing with 2 dimension (Length and Width). Volume, however, is unit cubed because you are now involving height as a third dimension.
Two.Two.Two.Two.
The standard deviation is defined as the square root of the variance, so the variance is the same as the squared standard deviation.
1. 1x1=1
25 squared is 25 x 25 or 625.
25 squared plus 49 squared is equal to 3,026.
The answer is 29. Bcause 2 squared is 4 & 5 squared is 25. 25+4=29.
Five squared is 25
25 squared= 25 X 25 = 625 625 X 30 = 18750
7 squared is 49 and 5 squared is 25. So the difference is 49-25=24
52 + 52 = 25 + 25 = 50
25
125x squared
25 squared is 625; the square root of 625 = 25
5 squared is 25 4 squared is 16 25-16= 9 the square root of 9 is 3.
