Enter the degree of the polynomial below.

10x4 + 4x5 + 7x2 + 6x7 - 8x6

A. 10

B. 5

C. 4

D. 7

For a term with one variable, the degree is the variable's exponent. With more than one variable, the degree is the sum of the exponents of the variables. Therefore, the degree of the given polynomial would be 7 or option D. It has the highest value among the terms. Hope this answers the question.
