Given : 


let's solve for f(x) × g(x) :



therefore, correct choice is : D
 
        
             
        
        
        
B, n to the 3rd power + 4n to the 2nd power +8n -16
        
                    
             
        
        
        
length is 8m
Width is 6.5m
<u>Explanation:</u>
Let, width = b
So, length = 2b-5
area = 52
We know,
area of rectangle = length X width
So,  =
 = 
On solving the above equation, we get
Width, b = 6.5m
length, l = 8m
