2) Appliances are connected in parallel
3) Appliances are connected in parallel (because in house , appliances are connected in parallel)
4) Advantage :- Such kind of connections assures that even if one or more appliances stops working , the working of other appliances will remain unaffected because in such connections , voltage remains constant 
Disadvantage :- Such circuits can draw more power which leads to high bill charges on electricity. Also such connections need more wiring.
 
        
             
        
        
        
3/4 + 3/4 = (3 + 3)/4 = 6/4 = 3/2
        
                    
             
        
        
        
42/(-3 * -2)
Multiply the -3 and -2
42/6

Answer:
you all have to divide by 2 
Step-by-step explanation:
602.88÷2= 301.44
 
        
             
        
        
        
This would be a question that would involve division. 
We do: (1,600 ÷ 4) and therefore, this would give us 

 just as we were looking for, and therefore, 
B would be your correct answer.
