Part B A different airplane travels at a constant speed of 600 miles per hour. • Write an equation that models the number of miles down, y. by this airplane given x hours. Identify the dependent variable and describe why it is the dependent variable • How many miles will this airplane travel in 2 5 hours? ​

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no
