(x+y)^2=x^2+y^2+2xy=73+2*24=73+48=121
⇒ (x+y)^2=121
        
             
        
        
        
To solve we need to use Pythagoras theorem ( 

 )
There are 2 possible lengths for x: hypotenuse or one of the 2 shorter sides.
Hypotenuse:
10^{2} + 21^2 = 

100+441= 
 

23.3≈x
Shorter leg:



= 441-100 

x≈18.47
 
        
        
        
You can use a common denominator and rewrite 3/5 divided by 1/10 as 6/10 divided by 1/10. 
Than you can think, “How many ___s are in ___? (Sorry, i don’t know this part)
3/5 divided 1/10 is 6
