The area of a square is A =  s^{2}, where s = length of a side of the square. You know the length of the square shaped traffic sign's side is s =<span> 2x-1. Plug that value into the equation for the area of the square and foil:
</span>A = s^{2} \\&#10;A = (2x-1)^{2} \\&#10;A = (2x-1)(2x-1)\\&#10;A = 4x^{2} - 4x + 1

KengaRu [80]

Answer:

Step-by-step explanation:

Correlation describes how strongly pairs of given variablé are related. In this case, a detailed analysis that was carried out shows that the number of days missed by employees explains 60% of the variation in salary increases and also impressed upon this fact that employees who missed more days of work during the year received smaller raises than those who missed fewer days.

From the analysis, we can draw a conclusion that there is a correction between days missed and variation in salary increase and that this type of correction is a negative correlation where an increase in the number of days missed will lead to a decrease in the raises awarded to each employee.
