Two trains, old steamy and chug-a-lug, are 290 miles apart from
each other and headed for the same station. they started toward the
station at 8: 00 a. m. if they are both set to arrive at 10: 30 a. m. and
old steamy is going 61.4 mph, how fast must chug-a-lug be going?
how far does old steamy have to travel?

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.

he is going to fill two shelves and the third shelf will only have five video games
