Which is the better buy a 3 pound ham for $5.70 or 5 pounds for $8.75

5 lbs for 8.75

Step-by-step explanation:

3 lbs of ham

Take the cost and divide by the pounds

5.70/3 =1.90 per pound

5 pounds

Take the cost and divide by the pounds

8.75/5 =1.75 per pound

The 5 pound is less per pound so it is a better but

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.
