For 19 I got z=15. And for 20 I got k=8.6
        
             
        
        
        
Answer:
B
Step-by-step explanation: 
4 or greater: 1/2 (4,5,6) 
4 or smaller: 2/3 (1,2,3,4) 
1/2 * 2/3 = 2/6 
2/6 = 1/3 
1/3 = 0.333
 
        
                    
             
        
        
        
<h2><u>EQUATION</u></h2><h3>Exercise</h3>
2(3 + 3y) + y = 11
First, apply the distributive property:
2(3 + 3y) + y = 11
6 + 6y + y = 11
6 + 7y = 11
Substract 6 from both sides:
6 - 6 + 7y = 11 - 6
7y = 5
Divide both sides by 7:


<h3><u>Answer</u>. The value of y = 5/7.</h3>
 
        
        
        
The answer to this question would be x=a2y2
