Answer:
A' = { 2,4,6,8,10,12,14,16,17,18,19}
A' U B = {2,4,6,8,10,12,14,16,17,18,19,7,11,13}
Step-by-step explanation:
A = {1,3,5,7,9,11,13,15}
B = {7,11,13,17,19}
Given:
The scale factor between two circles is 
.
To find:
The ratio of their areas.
Solution:
We know that, all circles are similar.
The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.
The scale factor is the ratio of the corresponding sides.
Ratio of areas of circles = Square of scale factor between two circles
Therefore, the correct option is D.

Answer:
Step-by-step explanation:
A third degree polynomial has a <em>total of three roots</em>, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
