Ok I don’t know what it’s the lesson 4, but you have to use “Usted” because you tell your mom how make your favorite recipe, for example you can say, “Mamá usted me puede hacer mi receta favorita de esta manera” you tell her how make.
I’m not sure what you need, but I can tell that the sentence it’s not correct, it supposed to be like this if you want it in the past form: Juan Carlos y Ana María pasaron la aspiradora. And like this if you want it in a present perfect form: Juan Carlos y Maria pasan la aspiradora. And if you want it in the form of future it should go like this: Juan Carlos y Maria pasaran la aspiradora. Hope it helped!:)
