Arrange the following polynomial into descending order for x, then interpret the degree of the 3rd term. 2xy4 + 2x2y - 3y2 + 10x3 a. 1. b. 2. c. 3. d. 5.

The arrangement should be based on the decreasing degree of the terms which may be determined by the variable x as it should come first in alphabetical order. The polynomial is then,

10x³ + 2x²y + 2xy^4 - 3y²

The degree is equal to the sum of the exponents. Thus, the answer is 5 and it is letter D.
