French language Q&A Forum

This was the question: 

From a drop-down multiple choice, I answered that it meant "I have everything" but I wasn't sure that was correct because of the "les"

The correct answer was, "I have all of them," but couldn't that be written as, "J'en ai tous?" That's where I got confused.

Si je changeais maintenant here you have used imparfait can I use passé composé here

For Indiana Jones lived through extraordinary adventures 

I used "a vécu par" for "lived through".  Is this incorrect?

Can anyone refer me to the lesson as to why "je me suis brossé les dents"   brossé has no extra e and the speaker is a woman. Has to do with "les dents" being the direct object, I think, but would love to read the lesson.

Can you also use ‘je ne pouvais pas dormir’ - if not why please..

Thanks

What word would we use in a more formal, or written context?

Salut a tous

If aux dents is plural how can it be translated as I have a toothache?

Merci
