Answer:
12 ft  and 25 ft
Step-by-step explanation:
a part is x ft and the other is (2x+1) ft
so 37= x  + 2x+1
    37= 3x+1
   -1        -1
    36= 3x
     :3     :3
    x= 36:3
   I=  x= 12 ft
  II= 2x+1=2*12+1=25 ft
  
 
        
             
        
        
        
Just subtract and then add then you should get your answer.

The domain of the function is the set of all the values of x that would allow the function to have real values. Since the radicand is x - 3, the value of x cannot be less than 3 because that would make the value of sqrt (x - 3) an imaginary number. Thus, the domain should be all numbers GREATER than or equal to 3.
