Mr. valenzuela new bottle of shampoo contains 60 ounces of shampoo. he uses 1/4 ounce of shampoo each time he washes his hair. which equation can be used to find x the number of washes after which 24 ounces will remain in the bottle

Step-by-step explanation:

We are given that:

Mr. Valenzuela new bottle of shampoo contains 60 ounces of shampoo.

He uses 1/4 ounce of shampoo each time he washes his hair.

Let x be the number of washes after which 24 ounces will remain in the bottle.

Then,  

Hence, the equation that can be used to find x,number of washes after which 24 ounces will remain is:

it would be 6xy and -16xy.

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.
