1. The first polynomial listed is just the number 9.
We can identify two key things here:
There is one term, so it's a monomial.
There are no factor's, so it has a degree of 0, or is constant.
Your answer is correct.
2. In the next polynomial, we can identify the same things:
There are three terms, so it's a trinomial.
The degree of the polynomial is determined by observing the higher power in a given term, in this case, it's three.
The prefix for relating to a multiple of three is cubic, we so know that this is a cubic trinomial.
Your answer is correct again, well done!
