A train can accommodate at most 80 passengers, economy class (x) and first class (y) passengers. To avoid making a loss the train must carry at least 10 economy class passengers and at least 20 first class passengers. Due to the number of item s the forts class passengers receive, the number of first class passengers should be at most three times the number of economy class passengers. first class tickets cost $5000 while economy class tickets $3000. state or describe what the variable x and y represents. state the objective function. list the constraints.​

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
