Answer:
Degree: 3
Leading coefficient=-18
Step-by-step explanation:
Remember that the degree of a polynomial is equal to the highest exponent on a variable, which in this case is x. By examining the polynomial, we find that the term -18x^3 has the highest degree of 3. Additionally, since the leading coefficient is paired with the highest degree of the polynomial (the term), we know that the leading coefficient is -18.
