Mr. watford owns two car dealerships. his profit from the first can be modeled with the polynomial c 3 − c 2 + 2c − 100, where c is the number of cars he sells. mr. watford’s profit from his second dealership can be modeled with the polynomial c2 − 4c − 300. a. write a polynomial to represent the difference of the profit at his first dealership and the profit at his second dealership. b. if mr. watford sells 45 cars in his first dealership and 300 cars in his second, what is the difference in profit between the two dealerships?

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
