Step-by-step explanation:
Total amount of apples in one bag:
[tex]x + y + z[/tex]
Hence, total amount of apples in two bags:
[tex]2(x + y + z)[/tex]
or
[tex]2x + 2y + 2z[/tex]
or
[tex]x + x + y + y + z + z[/tex]
Hence, B, D and E are correct.
A is incorrect because you are adding 2 more apples on top of the total amount of apples in one bag, and you cannot assume that there are 2 apples in each bag.
C is incorrect because you are multiplying the apples together, but you are supposed to add them up to find the total.
F is incorrect because you are finding 1/2 a bag.
