C, D. Amount of money earned and length of hair are totally unrelated so the it will be a nonlinear association. Age and number of siblings are also non related
Here is what I got for the answer
-18.375
you have to use the distance formula with the points and then add the distances
Side of a square = 4n
Side of the smaller square = 4n÷2 = 2n
Perimeter of one smaller square = 2n x 4 = 8n
Perimeter of 20 smaller squares = 8n x 20 = 160n
------------------------------------------------------------------------------
Answer: Perimeter of all the 20 smaller squares = 160n

For every action you want to record the "Distance", you do not want to find the displacement. 210 feet + 300 feet = 510 feet. His total distance traveled is 510 feet
Displacement however would be -90 = 210 - 300 because he is now -90 feet from where he begun. The reason the 90 is negative is because he is lower now than he was before because the downward movement was greater than the upward movement.
