4 over 5 is the correct answer
        
                    
             
        
        
        
2r + 2r + 5 + r + 4r - 3 = 38
9r + 5 - 3 = 38
9r + 2 = 38
9r = 38 - 2
9r = 36
9r/9 = 36/9
r = 4cm
Done!

Answer:
   168 cubic inches
Step-by-step explanation:
The formula for the volume of a pyramid is ...
   V = (1/3)Bh
where B is the area of the base, and h is the height.
The base is a rectangle, whose are is given by the formula ...
   A = LW
   A = (8 in)(7 in) = 56 in²
Then the pyramid volume is ...
   V = (1/3)(56 in²)(9 in) = 168 in³
The volume of the pyramid is 168 cubic inches.
 
        
             
        
        
        
2 * 10^2
Divide the first numbers, which are 6 and 3, to get 2. Then, subtract the powers of the exponents, which are 5 and 3, to get 2.
 
        
             
        
        
        
Answer with Step-by-step explanation:
We are given that

We have to explain that why the function is discontinuous at x=2
We know that if function is continuous at x=a then LHL=RHL=f(a).

LHL=Left hand limit when x <2
Substitute x=2-h
 where h is small positive value >0


Right hand limit =RHL when x> 2
Substitute 
x=2+h


LHL=RHL=
f(2)=1

Hence, function is discontinuous at x=2
