How much does 2 eggs cost if a case of eggs costs $25.23

$4.20

Step-by-step explanation:

Number of eggs in a case - 12

Total cost of the case - $25.23

Cost of 1 egg - $2.10

25.23 ÷ 12 ≈ 2.10

2 eggs = $4.20

2.10 x 2 = 4.20

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.
