Answer:
The slope of the line is 2
Step-by-step explanation:
y=2x+1, compare it to the slope intercept form of a line, y=mx+c, the slope will be 2
 
        
                    
             
        
        
        
Step-by-step explanation:
33x
 
        
             
        
        
        
If the face is a square, then (l*l)
If the face is a triangle, then (b*h)(1/2)
If the face is a rectangle, then (l*w)
If the face is a circle, then (r²)(3.14)
You can then add all these faces up to get the total surface area of the prism.
 
        
             
        
        
        
PEMDAS so (9+15)= 24 , 24/3 = 8 , 8+2 = 10
