Answer:
c ln (x^3/y^3)
Step-by-step explanation:
3 ln x - 3 lny
We know that a ln b = ln b^a
ln x^3 - ln y^3
We also know ln a - ln b = ln (a/b)
ln (x^3/y^3)
 
        
             
        
        
        
So uh uhm yes uhhhhhhhhhhhhhhhh
        
                    
             
        
        
        
The answer should be 5 degrees. The temperature starts at 8 degrees and decreased to 3 degrees. Therefore you find the missing addend which in this case is 5 degrees. 8-3=5
        
                    
             
        
        
        
The second one is the answer
