At maximum speed, an airplane travels 2400 miles against the wind in 6 hours. flying with the wind, the plane can travel the same distance in 5 hours.
let x be the maximum speed of the plane and y be the speed of the wind.
what is the speed of the plane with no wind?

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
