Answer:
Everything looks good but change something in the second sentence on question 4.
Step-by-step explanation:
I mean this in a nice way, what would you be washing? The sentence ultimately describes that you're washing your backpack. If you're washing you're hands it would be: laver mes mains. If you're washing your face it would be: laver mon visage. If you're freshening up it would be: se rafraîchir, but looking at the sheet you seem to be starting french, which is great! For short terms, needing a definition, or conjugation I would recommend wordreference.com . It's great for people starting to learn french or a refresher. Good luck!
