Answer:
D
Step-by-step explanation:
Matrix D represents 3 x 3 identity matrix.
Because all elements of principal diagonal are 1 and others are zero.
To determine the degree of a polynomial, you look at every term:
- if the term involves only one variable, the degree of that term is the exponent of the variable
- if the term involves more than one variable, the degree of that term is the sum of the exponents of the variables.
So, for example, the degree of
is 55, while the degree of
is 
Finally, the term of the degree of the polynomial is the highest degree among its terms.
So,
is a degree 2 polynomial (although it only has one term)
similarly,
is a degree 3 polynomial: the first two terms have degree 3, because they have exponents 2 and 1.
