Two airplanes leave the airport at the same time, flying in opposite directions. One plane flies 100 miles per hour faster than the other. They fly for 4 hours and end up 2,000 miles apart. How fast do they each fly?

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

i think the answer is d im not sure

hello, never fear papaguy is here!
