If the <em>n</em>-th term of the sequence is given by <em>n</em> ² - 2, then the 5th term is obtained by simply replacing <em>n</em> with 5 :
5² - 2 = 25 - 2 = 23
 
        
             
        
        
        
Answer:
A is true.......................b is false....................and c is false
Step-by-step explanation:
 
        
             
        
        
        
For this case we have the following equation:
 Density = mass / volume
 If the volume is the same, then the object with the greatest weight will be the one with the highest density.
 You must know the type of way to know the value of the density.
 Answer:
 The weight of the blocks will depend on the density if the volume is the same.
        
                    
             
        
        
        
Answer: The system consists of parallel lines
Step-by-step explanation:
Given system of lines :
  
 

Substitute  in
 in  ,  we get
,  we get
 , which is not true.
 , which is not true.
That means , system has no solution.
i.e. they are representing parallel lines. [Parallel lines do not intersect and hence they do not have solution.]
