Answer:
10x.
Step-by-step explanation:
It is given that,
JK = 3x
LM = 12x
JM = 25x
Let as consider the line as shown in the below figure.
From the figure it is clear that,
 
 
 
 
 
Therefore, the length of KL is 10x.
 
        
             
        
        
        
The Formula would be A=3.14rr
 Which is A=3.14(3)(3)
The answer is 28.26
        
                    
             
        
        
        
Answer: 3y3+7y2+−4y+3
Step-by-step explanation:
3y2+y3+−5+4y2+−4y+2y3+8
Combine Like Terms:
=3y2+y3+−5+4y2+−4y+2y3+8
=(y3+2y3)+(3y2+4y2)+(−4y)+(−5+8)
=3y3+7y2+−4y+3
