A lion needs to eat at least 20 pounds of food each day. The zoo feeds the lion using canisters that
each contain 4 pounds of food. The lion has already
consumed 8 pounds of food. How many more
canisters x of food does the lion need to eat? Write
and solve the inequality. How will I write the inequality to solve?

3 more canisters.

Step-by-step explanation:

20 divided by 4 ( 4 pounds per container) is 5. When you divide 8 by 4, you get 2. 5-2=3. 3 more canisters! :) hope this helps!

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.
