Can someone help me please

9514 1404 393

  330 miles

Step-by-step explanation:

The distance formula can be used to find the number of grid units between points.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

AC = √((-2-11)^2 +(6-(-2))^2) = √((-13)^2 +8^2) = √(169+64) = √233 ≈ 15.264

CD = √((-8-(-2))^2 +(9-6)^2) = √((-6)^2 +3^2) = √(36 +9) = √45 ≈ 6.708

Then the total distance in miles is ...

  (15.264 units +6.708 unit)(15 miles/unit) ≈ 329.59 miles

Rounded to the nearest mile, the distance is 330 air miles.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
