Answer:
the answer is 15
Step-by-step explanation:
density= total population/surface area
density= 375/5^2
density=375/25=15
 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
5x² - 3 - (x² - 4x - 8)
5x² - 3 - x² + 4x + 8
4x² + 4x + 5
 
        
             
        
        
        
The answer is The equation 3.5|6x – 2| = 3.5 has one solution
 
        
                    
             
        
        
        
You could interpret them as system of equation and answer the question easily
from A 
-4x + y + x + w =1
write in same form from A 
as this system has five variables and four of them are unknowns it means the unique solution is not possible 
So, det (A) = 0
