Tony and Ian are each buying a new car. There are three upgrades that they can select: metallic paint (10 different choices) alloy wheels (5 different choices) music system (3 different choices). Tony selects all 3 upgrades. Find how many different possible combinations there are.

the answer is 0.071

good luck! : d

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.

other answer is correct. i had used the radius of the radius somehow. a website:
