(a) Terms are the expressions that are ADDed together. So view the expression as
The terms are then 3x^2y, -2xy, x, and -1.
The coefficients are the numerical part of each term: 3, -2, 1, and -1.
The degree of each term is the sum of the exponents of all the variables in the term: 3 (2 x's and 1 y), 2 (1 x and 1 y), 1 (only an x), and 0 (no variables).
The degree of the polynomial is the highest degree of any term: 3.
-------------------------------------------------
240,000 = 2.4*10^5
(2.4*10^5)/(4*10^4) = 0.6*10^1 = 6 hours
