Answer:
The subjects are: red, white and blue.

Explanation:

As you may already know, the verb is the word that determines an action that is being performed. In the sentence shown in the question above, the verb is the word "are." In this case, the subject is the words that are performing the action of that verb, which are the words "red, blue and white."
The predicate. it is everything that is being said about the subject of the sentence. In this case, the predicate is "are the colors of the flag."
