the correct form of the plural in the examples are :
glasses, taxes, atlases, porches
the reason is because when a regular noun ends in S,SH,CH or X, you need to write ES to make the plural.
the second bit is more formal, " You're six years old, aren't you?"
because, the other sounds very demanding or imperative, like as if you have to answer the question. so, it has to be the second line.
I’m pretty sure it’s Eden
