Unidad 3 leccion 1 apaguen la luz al salir de una hbitacion (apagar) ayuda a sus companeros para reciclar las latas

Pidan ayuda a sus compañeros para reciclar las latas.

Explanation:

To complete this exercise, you have to write the sentence given using the ''ustedes command''.

The Spanish ''ustedes command'' can be used for both affirmative and negative commands. The ''ustedes endings'' are different for each infinitive verb ending. For example, in this case the verb ''pedir'' (infinitive of the verb ''pidan'' that is the correct answer) ends with ''IR'' so the ''ustedes ending'' is ''-AN''. Therefore, the correct answer is ''PIDAN''.
