<h3> Answer:</h3><h3>The simplest form of 477/636 is 3/4.</h3><h3>The simplest form of 361/418 is 19/22</h3>
 
        
        
        
5.2+4.8= 10
So it has to be 20 I think

 To solve the above, we need to follow the steps below;
4k+2 can be factorize, so that;
 4k +2 = 2 (2k + 1)
k² - 4  can also be be expanded, so that;
k² - 4 = (k-2)(k+2)
Lets replace  4k +2  by  2 (2k + 1)
and 
k² - 4 by  (k-2)(k+2)   in the expression  given
 ×
  ×  
  ×
   ×  
(2k+1) at the numerator will cancel-out (2k+1) at the denominator, also (k-2) at the numerator will cancel-out (k-2) at the denominator,
So our expression becomes;  

 Therefore,  ×
  ×   =
   =  
 
        
                    
             
        
        
        
First off Jackson's mom sucks for limiting game time and second of the answer is 30 minutes. If 9 is 30 percent that means 3 is 10 percent. 3 times 10 is 30. So 30 minutes
        
                    
             
        
        
        
The answer would be x = -7.
Hope this helps!
