Mrs. Sloan draws two figures on the board. Allen says that figure Z is dilated to form
figure Z' using a scale factor of 3 and point X
as the center of dilation. What mistake did
Allen make? What is the correct scale factor?
Explain your reasoning.

b

Step-by-step explanation:

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.

his chances of getting a coin of higher value is 4/19
