Fill in the blank with the appropriate past-tense form of the verb in parenthesis.Nous tous nos devoirs. (finir)

Finir forms the passé composé with avoir: avoir + fini. With the subject nous, avoir becomes avons, so the sentence is “Nous avons fini tous nos devoirs.” “Sommes fini” uses the wrong helping verb for finir.
