30, you could just multiply both numbers, but it's also better to list out the factor until both match

Step-by-step explanation:
Easy pythagorean theorum question.
The law states that "A squared plus B squared, equals C squared."
A and B are the two sides that border the 90 degree mark.
C is the hypotenuse or the longest side/diagonal.
Since we know C and A (I chose to use A because why not) we can fill in the equation with what we know
2^2 + ?^2 = 
So 
4 + ?^2 = 
Since the 13 is already squared in side of a root, it stays as 13
4 + x^2 = 13
4 - 4 + x^2 = 13 - 4
x^2 = 9
x^2 root = root of 9
x = 3
The missing side is 3.
Or you could use an online calculator xD
 
        
             
        
        
        
68%. There is a 17% faliure rate for a computer, so if you buy 4 computers... 
17 x 4 = 68% 
Correct me if Im wrong!
        
             
        
        
        
As a mixed number it’s 7 6/9 -not too sure about improper fraction. just know that repeating decimals always have a 9 as the denominator -hope that helps :)
