The US courts are reviewing a case to see whether a work has been refused fairly. What is an example of something they might consider when trying to decide whether the use was fair?

The Purpose and Character of the usage of the work.

Step-by-step explanation:

In the United States of America, there is a terminology used in court called Fair use. This is a law in the USA that permits a limited use of one or more copyrighted materials without the need to first acquire permission from the holder of the copyright.

Thus, an example of something they might consider when trying to decide whether the use was fair is:

The Purpose and Character of the usage of the work.

This is because the original purpose of the work may have been altered to mean something new or different or it was just copied exactly into another work.

So knowing the purpose and character of usage of the work or material in question would be something they would consider

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
