The rule at Anna's house is that if she eats all of her vegetables and does all of her chores each day, she earns 2 hours of internet time which she can save. Anna started her week with 3 hours saved. If she eats all of her vegetables and does all of her chores each day for 4 days straight, how many hours does she have after the 4 days if she uses 6 hours of her internet time?

She has 6 hours left.

Step-by-step explanation:

She started with 3 hours saved and got 2 more hours for each day that she did her chores and ate her vegetables.  Since she did her chores and ate her vegetables 4 days that means that in total she gained 8 hours (4 * 2) plus the ones she already had saved.   So 8 + 3 = 12 - 6 = 6

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.
