    • @isaiahphillip4112
      @isaiahphillip4112 7 лет назад +3

      It should be the square root of 16, you don't need the formula to figure this one out.
      You can see that since they have the same y value (-10) they will be on the same x axis, therefore the distance between them is simply the absolute value of the difference between the x values |-6 - (-2)| = 4
