Mr. lewis sees a red light ahead and applies the brakes on his car. the car travels 300.5 feet before coming to a stop. for each foot the car travels during this time, its speed changes by −0.2−0.2 miles per hour.

what is the total change in the car's speed during that time?

drag and drop the correct answer into the box.

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.
