Astudent is attempting to factor a polynomial. sample mathematical work is shown below. which statement best applies to the sample mathematical work?

given 3x + 6, the factors of the first term are 3 and x, and the factors of the second term are 1, 2, 3, and 6. thus, the greatest common factor is 3. dividing through by the greatest common factor, i get x + 3. thus, the factored polynomial is 3(x + 3).

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers.a) one of the 400 passengers is selected uniformly at random.let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem
