5 times 11=55
15 times 3 is 45
add together is 100
5+15 is 20 questions
 
        
                    
             
        
        
        
1 cm = 20 km
so 3.5 cm would equal : 3.5 * 20 = 70 km <==

➷ Expand them all to see if you get the expression:
2(3x - 4) ==> 6x - 8
2(3x + 4) ==> 6x + 8
2(4x + 6) ==> 8x + 12
2(3x + 8) ==> 6x + 16
As you can see, the correct option is B. 2(3x + 4)
