Answer:
(x + 2)(x² - 2x + 4)
Step-by-step explanation:
x³ + 8 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
x³ + 8
= x³ + 2³
= (x + 2)(x² - 2x + 4)

Answer:
A. negative correlation
Step-by-step explanation:
Let two variables x and y, the correlation coefficient r measure to what degree the variables x and y are related.
--- If this coefficient is positive then the relationship will be positive. This means that even an increase in the variable x will produce an increase in the variable y. In the dispersion diagram the points will be grouped, simulating a line of positive slope.
--- If this coefficient is negative then the relation will be negative. This means that even an increase in the variable x will produce a decrease in the variable y. In the dispersion diagram the points will be grouped, simulating a negative slope line.
In the diagram shown it can be noted that as the variable x increases the variable y decreases.
Therefore it can be concluded that the correlation between x and y is negative. The correct option is option A
