Acar left sacramento, california, and traveled at an average speed of 95 km/h to redding california. the distance between the two cities is 260 km. how many hours was the car traveling?

About 2 hours

(About 2 hours and 25 minutes exactly)

I added minutes anyways

260 divided by 95 = 2 Remainder 25

                                 Hrs                  Mins

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.
