because 3 pieces 
divided by 2 because there half pieces.
 
        
                    
             
        
        
        
Answer:
1. No vertical compression or stretching but will open up downward.
2. 1/4 vertical stretch
3. 4 vertical compression
Step-by-step explanation:
Any time your dealing with vertical stretching or compression it will always be the number before the parentheses. 
So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression
2. Is the 1/4 is a vertical stretch 
3. 4 is a vertical compression. 
Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be. 
 
        
             
        
        
        
Lets first simplify the dimensions of the rectangle
length = 7
breadth = 

 = 

 = 0.6
The area of rectangle = length * breadth
so, area of rectangle = 7 * 0.6  
Area of rectangle = 4.2
Hope it helped you.. :D
 
        
        
        
76 sodas and 34 hot dogs were sold by the vendor.
Step-by-step explanation:
Given, 
Total sodas and hot dogs sold = 110 
Let, 
x be the number of sodas sold 
y be the number of hot dogs sold 
According to given statement; 
x+y=110     Eqn 1
y = x-42    Eqn 2
Putting value of y from Eqn 2 in Eqn 1

Dividing both sides by 2

Putting x=76 in Eqn 1

76 sodas and 34 hot dogs were sold by the vendor.
