Una fábrica produce tres tipos de balones de fútbol, con un costo mensual de
$24,250.00 por cada 1125 balones. Los costos de fabricación son $ 40.00, $ 30.00 y $
20.00. Estos balones se venden en $ 160.00, $ 120.00 y $ 100.00, respectivamente.
¿Cuántos balones de cada tipo se fabrican si la ganancia mensual es de $ 92,750.00?

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.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
