Volume of a rectangular prism = l × w × h.
In this case, 
V = 270 cubic feet
l = 15 feet
w = 4 ft
h = ?
Plug our values into the volume formula.
270 cubic feet = 15 feet × 4 feet × h. 
Simplify the right side
270 = 60 × h.
Divide each side by 60.
4.5 = h
The height is 4.5 feet.
 
        
             
        
        
        
Answer: the value of "x" is 4 
 
        
                    
             
        
        
        
Y = 3bx - 7x
y = x(3b - 7)
Divide each side by 3b - 7 (assume that it is not zero).

 Answer:
c
Step-by-step explanation:
From the graph as x gets larger and becomes positive f(x) approaches 0 so the answer is C.
