3.25 hours you take 4680÷1440 = 3.25
        
             
        
        
        
answer:
a. 16.
step-by-step explanation:
32 = 2*2*2*2*2
48 = 2*2*2*2*3
picking out the common factors:
gcf = 2*2*2*2 = 16.
 
        
             
        
        
        
The solution of the equation (√x-8) + 2 = 7 is x = 13.
According to the given question.
We have an equation 

Since, we solve the above equation for x .
Therefore, 

⇒ (√x - 8) = 7 - 2
⇒ (√x - 8) = 5
Squarring both the sides.
⇒ x - 8 = 5
⇒ x = 5 + 8 
⇒ x = 13 
Hence, the solution of the equation (√x-8) + 2 = 7 is x = 13.
