Step-by-step explanation:
A monomial is a polynomial that has only one term.
A binomial is a polynomial that has 2 terms
A trinomial is a plolynomial that has 3 terms.
This one has 2 terms, so it's definitely a binomial
The degree of a polynomial is given by the highest power of all terms. If a term has 2 different variables, the degree of that term is the sum of the powers of the variables:
7xy --> degree 2
-15y³ --> degree 3
Therefore, the degree is 3
Answer:
a. binomial with the degree of 3
