The answer to this is x=3
        
             
        
        
        
O= 4 & -4 
Explain: it shows on the paper
        
             
        
        
        
circular cardboard with an area between 154 in² and 616 in²
Radius is between 7 inches and 14 inches. ⇒ A) 7 < r < 14
√18 + √2 = √9 *2 + √2 = 3√2 + √2 = (3+1) √2  = 4√2
D) It is irrational and equal to 4 multiplied by the square root of 2.
 
        
                    
             
        
        
        
So remember that the distance formula is  .
 .
1.

Distance between (4,-5) and (4,-2) is 3 units.
2.

Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.
