QR. because if BCDE is congruent to OPQR then the sides and angles will be the same also by either sss, sas, asa, or aas depending on how the shape is.
        
                    
             
        
        
        
Alright, so the first thing I would do is find the LCM of the dividends, which is 20.  So we have 10 15/20 and 6 16/20.  You can either leave it there and just carry the one (20 in this case) for 3 19/20.
If you multiply 10 by 20 and add 15, or 6 by 20 and add 16 (which I think is easier) you get 215/20 - 136/20 = 79/20.  It can be simplified from here if you teacher wants it in the future.
        
                    
             
        
        
        
The mathematical expression for the given statement is 50 + 10x
<h3>How to write a mathematical expression for this statement?</h3>
The given parameters are:
Initial distance = 50 laps
Rate of increment = 10 laps each week
Represent the number of weeks with x
So, we have:
Number of laps = Initial distance + Rate of increment * Number of weeks
This gives
Number of laps = 50 + 10 * x
Evaluate
Number of laps = 50 + 10x
Hence, the mathematical expression for the given statement is 50 + 10x

Area of a square = pie r^2.
Radius = sqrt 484 = 22.
Diameter = 2 r = 2 x 22 = 44.
Hope this helps!
