Billy makes $246 got 8 hours of work as a math tutor. He wonders how much money he would make if he worked 75 hours.

$2306.25

Step-by-step explanation:

To get this, first find out how much money he makes in an hour by dividing $246 by 8 hours. You should get $30.75. Then multiply $30.75 by 75 hours and you get $2306.25.

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.
