Ustedes estan en la sala de clases
Answer:
Donde estudian Isabel y sus amigas?
Explanation:
Instead of saying where they study(which is in the library) you would ask where they study. Sorry if I'm too late.
Tu eres guapo is the correct tense
5 is true 6 is also true
Estar is to be. But estar can be estoy, estas, esta, estamos, and estan. You can ask “Como estas” which is “how are you”
Estar is also used to express a person or item's geographic or physical location.
