Option B;
A suitable x-coefficient for a quadratic function that factors into a perfect square has to be even.
        
                    
             
        
        
        
Step-by-step explanation:
10^2 = 100
10^-2 = 1/100 ➡ 0.01
 
        
             
        
        
        
<span>valid. She used a representative sample
</span>because she correctly found the average and 18,000 is a reasonable number to get for a the problem
        
                    
             
        
        
        
Answer:
5 units. Since they have the same y coordinate the x coordinate determines the distance from each other. In the case 9-4=5.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The rule with like bases is that when you multiply them you add their exponents. 

Therefore, our final simplification is
