Mathematics

Answer:

D. 25x² - 20x + 4

Step-by-step explanation:

The formula for the area of a square is: A = s², where s = a side length of the square since all side lengths of a square are equal.  In this case, the side length is represented by '5x', so the original area is A = (5x)² = 25x².

Since Kelly is cutting off one inch from each side of square, this will actually take off 2 total inches from each side, making the new side length '5x - 2'.  We can now put this expression in for the values of 's' in our formula for area and use distributive property to solve:

A = (5x - 2)² = (5x - 2)(5x - 2)

Distribute using FOIL:  25x² - 10x - 10x +4 or 25x² - 20x + 4

Which statement is not true about the data shown?
Dmitrij [34]

Answer:

believe it is "the median is 82."

Step-by-step explanation:

55,66,82,89,90,92

there are 6 numbers so in order to find the median here you would have to add 82 and 89 together and then divide by 2.

82+89=171

171/2=85.5

hence "the median is 82." is the right answer
