hi
this car is as much efficient than this one =
cette voiture-ci est aussi performante que celle-ci.
Comparatif d'égalité=
English = as + adjective+ as
French = aussi +adjective + que
autant +nom + que
1) false because performant is an adjective and hes to agree with car= feminine = performante
2) false = autant de performante que = should be autant de performance (noun) que
3) correct
5) false = verb avoir is wrong. It has to be être
with avoir , you should use a noun = cette voiture-ci a autant de performance (noun) que celle ci
hope this helps to understand !!!
