A model train layout has an inner track and an outer track. Train A can travel ſ of the way around the outer track in 30 seconds. Train B can travel of the way around the inner track in 30 seconds. If the
trains go for 12 minutes each, how many more complete circuits of its track will Train A complete than
Train B?

answer: procent 54 wynosi 33,33%

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.

hope this : )
