Answer:
Option C.
Step-by-step explanation:
Solid in the given picture is a rectangular prism and a rectangular prism has 6 faces. Each face is formed by joining 4 vertices of the prism.
All the faces joining four vertices are: AFGB, BGHC, ADEF, DCHE, FEHG, ADCB.
From the given options,
Option (C). ADEF will be one of the face of the solid.
 
        
             
        
        
        
Answer:13/12
Step-by-step explanation:
2/3=8/12. 1 3/4=7/4=21/12. 21/12-8/12=13/12
 
        
                    
             
        
        
        
Answer:
Part 1) Vertical line : 
Part 2) Horizontal line :  
Step-by-step explanation:
Part 1) Write the equation for the vertical line passing through the point (1,-4)
we know that
The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it 
so
The x-coordinate is 1
therefore
The equation of the line is 

Part 2) Write the equation for the horizontal line passing through the point (1,-4)
we know that
The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it 
so
The y-coordinate is -4
therefore
The equation of the line is 

 
        
             
        
        
        
The answer is 125. Just for you to understand all you have to do is 20 *____ =625 in this case 20*125=625 :)
