Please I really need help with this

For number 9, the answer would be ha escrito. For number 10, the answer would be han vivido.

Explanation:

In number 9, you need to write escribir (write) in el presente perfecto, so (haber + escribir). In english the complete sentence would be: The author has written a new book. Has (in english) is the [haber] part,and you always need to change that to make the subject and the verb agree. The same thing happens in Spanish. All presente perfecto means is that the verb needs to match present tense and it needs to have haber (which needs to agree with the subject). Same thing happens with the second sentence except the subject is plural. Thus, you have: Juan and Marisol have lived in Buenos Aires for many years. Normally, you use [have] when you have a plural subject, in spanish have would be han. Vivido (lived) matches present tense.

he is taking the trash out like a good person.
