3.) 3 faces. 4 edges. 3 V
4.) 5 faces. 5 edges. 3 V
5.) 2 faces. 1 edge. 1 V
6.) 3 faces. 0 edges. 1 V
7.) 1 face. 0 edges. 2 V's
I'm iffy on the V's. 
        
             
        
        
        
Answer:
 85 pens  
Step-by-step explanation:
The computation of the number of green pens sold is shown below;
As the number of black pens, red pens, and green pans is 3:5:6
And, the ratio of sold of black pens, red pens, and green pans is 7:3:4
So, the ratio of pens in a number of pens is 
= 3 × 7 : 5 × 3 : 4 × 6
= 21: 15 : 24
= 7: 5 : 8
And, the total of 212 pens are sold 
So, the number of green pens sold is 
= 8 × 212 ÷ (7 + 5 + 8)
= 85 pens  
 
        
             
        
        
        
It goes zero positive negative. that is from left to right
        
             
        
        
        
Answer:
Growth
Step-by-step explanation:
since the (1.05) is bigger than 1 it is growth but if it was lower then  1 it would be decay .
 
        
             
        
        
        
The answer should be 103. Because the interior angles of all triangles add up to 180 degrees, you can just add together the two known interior angles; subtract them from 180; and then find the supplement.
