Tenemos una parcela de terreno agrícola que deseamos vallar. La parcela tiene un perímetro de 1km, 8hm, 80dam, y 80m y 20.000 dm y 0,50€ si compro más de 30.000 dm ¿Cuánto nos cuesta vallar la parcela?

your answer would be 10x - 1

0 is its x and y coordinate

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.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
