Answer:
Not a polygon
Step-by-step explanation:
[(3x+12)•(4x+4)]-(3x+8)-(4x)
[12x² + 12x + 48x + 48] - 3x - 8 - 4x
12x² + 60x + 48 - 7x - 8
12x² + 53x + 40
This is a degree 2 (quadratic) polynomial, not a polygon.
A polygon is an n-sided figure.
Example: A rectangle --> A four-sided polygon

Answer:
What is the probability formula?
Image result
In general, the probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
Answer:
qualitative
Step-by-step explanation:
Qualitative data is one which is non numerical in nature. The data which has characterizes types of units under observation. Here also in the given question the when the colors of test tube are compared we look at the specific color of certain test tube. When the absorption ratings for the test tube are compared we are looking at the capacity of the test tube. This represents the characteristic of certain test tube. This is an example of qualitative data.
