Whether a definite or indefinite article

Nous nous sommes brossé les cheveux. 

This was the answer. Why doesn't "brossé" end in "s"?

vraiment ou vraiement?  I think it is vraiment -

This is actually confusing, as it seems the sentence might be incorrect. I keep wondering why it isn't  Quelles chaussures ils/elles plaisent? Or  Quelles chaussures tu plais?

Penultimate prompt is in fact for the last sentence.

In the phrase 'vous receviez des amis à déjeuner' is 'déjeuner' a verb or a noun?

What is the meaning of the ‘t’ in the phrase ‘ouvre-t-on’?

The use of "aussi bien que" puzzles me.  Wouldn't "ainsi que" be the correct usage in this context such as:

L'Angleterre, ainsi que la France, a combattu l'Allemagne en 1914.England, as well as France, fought Germany in 1914. 
In contrast, "aussi bien que", means a comparison of abilities such as:
L'Angleterre a combattu l'Allemagne aussi bien que la France en 1914.England fought Germany as well as (as efficiently as) France in 1914.

J'habite aux Saudi Arabie. C'est vrai?
