Answer: The answer you are looking for is option A which would be 3 - 7x^5 +x^2

Step-by-step explanation: It is a 5th degree trinomial because, there are three terms in this equation being 3, 7x^5, and x^2; this makes it a trinomial becuase there are three terms. What makes this a 5th degree is the fact that the highest exponet is 5.

A 5th degree polynomial means that when simplified, the variable is to the 5th power. A trinomial is when there are three different components.

Therefore, your answer is A because there is an x to the 5th power, and three different components (3, -7x^5, and x^2)
