Answer: c. Describe the data

Step-by-step explanation:

Description of data involves the use of descriptive statistics to analyse/summarize a set of data (from samples) generated during a research.

Some of the process involved in the description of data involves the measure of central tendency ( averages, mean, median mode) and also measure of dispersion and graphing. Therefore, the case above described the data collected.

Let the polynomials A = 7x² + 3xy and B = -3xy .
bija089 [108]

Answer:

– 21x^3 y – 9x^2 y^2 e) is your answer

Step-by-step explanation:

Solve the following system for A and B:

{A = 7 x^2 + 3 x y

B = -3 x y

Express the system in matrix form:

(1 | 0

0 | 1)(A

B) = (7 x^2 + 3 x y

-3 x y)

Write the system in augmented matrix form and use Gaussian elimination:

(1 | 0 | 7 x^2 + 3 x y

0 | 1 | -3 x y)

Collect results:

Answer: {A = 7 x^2 + 3 x y  , B = -3 x y

then we multiply the results (7 x^2 + 3 x y) ( -3 x y) =  – 21x^3 y – 9x^2 y^2
