dave and sandy hartranft are frequent flyers with a particular airline. they often fly from city a to city b, a distance of miles. on one particular trip, they fly into the wind, and the flight takes 22 hours. the return trip, with the wind behind them, only takes 1 1/2 hours.

2 hours. if the wind speed is the same on each trip, find the speed of the wind and find the speed of the plane in still air.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
