Isaac keeps track of the total miles the cross country team runs per week. He has accumulated the following data: (1, 24), (2, 36), (3, 54), (4, 81) What is the common difference or ratio? The common difference is 12.
The common difference is 20.
The common ratio is 0.67.
The common ratio is 1.5.

Step-by-step explanation:

the answer to the expression is 83

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.
