I will pick brainliest first come, first serve! I need help! Give me an answer that makes sense!
nordsb [41]

Step-by-step explanation:

Total amount of apples in one bag:

x + y + z

Hence, total amount of apples in two bags:

2(x + y + z)

or

2x + 2y + 2z

or

x + x + y + y + z +  z

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.
