A square with a perimeter of 48 inches would have 12 in sides, while a triangle of the same perimeter would have 16 in sides. The ratio would be 16/12 which simplified to 4/3.
        
             
        
        
        
No her estimate is to low because if you multiply 15.5 by 12 you get 186
        
                    
             
        
        
        
A) 18x2 = 36
hope I helped 
Best of luck :)
        
             
        
        
        
Answer:
PV= Max Loan amount = PMT*B(i,T) and PMT = 1200. Calculate B(i,T) = B(6%/12, 360)
=(12/.06)(1-(1/(1.005))360)  I will let you complete the calculation
Step-by-step explanation:
 
        
             
        
        
        
I'm assuming that you meant 4x+1=3x?
Subtracting 4x, we get 1=-x.  Multiplying by -1, we get x=-1 as the solution.
