Answer:
Leading coefficient: 20
Degree: 4
Explanation:
The leading coefficient of a polynomial is the coefficient of the term with the highest degree. In the given polynomial, the term with the highest degree is 20v^4, and its coefficient is 20.
Therefore, the leading coefficient is 20.
The degree of a polynomial is the highest power of the variable in any of its terms. In the given polynomial, the highest power of v is 4, which is the degree of the polynomial.
So, the leading coefficient is 20, and the degree is 4.
