Eliana drove her car and used 9 liters of fuel. she wants to know how many kilometers she can drive on 22 liters of fuel. she assumes her car will continue consuming fuel at the same rate.
how far can eliana drive on 22 liters of fuel?

9 liters of fuel covered   81 km

1 liter of fuel would have covered  81/9  km  = 9 km

22 liters of fuel would then cover   =   22 * 9  =  198 km.

i think you should think about the question and not look online.

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.
