a car travels along a straight road, heading east for 1 h, then traveling for 30 min on another road that leads northeast. if the car has maintained a constant speed of 58 mi/h, how far is it from its starting position? give your answer correct to 2 decimal places.

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

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.
