The answer is 40 cookies in 2 hours because if she can make 120 cookies in 6 hours. 120/6 is 20. So she make 20 cookies in 1 hour sooooo 20+20=40. So the answer is 40 cookies. ✨
The change in x, as we move from left to right, is 7-4, or +3.
The corresponding change in y is -2i-2i = -4i.
Use the Pythagorean Theorem to find the length of this line segment:
d = distance from 4+2i to 7-2i= sqrt( [3]^2 + sqrt( [-4]^2 ) = sqrt(9+16) = 25 (ans.)
The answer is 306.0000 square units.
