Question

all of the following are equivalent, except A. (12+3)x
B. (12+3x)x
C.15x
D. 12x+3x

Answer 1

don't no because I study in 6th class thats why

Answer 2

hey dear bud

ur answer is

b) (12 +3x)x

because when we add it , it gives

15x^2 where as the other three expressions are like because when we add them they gives same answer

as:

1,(12+3)x=15x

3.(15x)

4.(12x +3x)=15x

from above, as we can see that there is same answer as 15x as compared to the answer of part 2. i.e, 15x^2

hope u can understand nd it will help u dude
