Answer:
[-4, 2½]
Step-by-step explanation:
The quickest way to do this is to calculate how far apart each corresponding coordinate is, then take HALF of that range:
From -4 to -4 → 0
From 3 to -8 → 11
-3 + 5½ = 2½ [y-coordinate] → [-4, 2½]
** Just in case you were wondering why I did not calculate zero, zero is neutral, so it stays zero.
I am joyous to assist you anytime.
Hey! To do this you have to do 0.03 x 800 to get 24. Good luck!

The answer is Negative use the clue worlds like the word (descended) 2.23 ft every hour for 3 h.
so at the end he was at -6.69 ft below from were he started.
Answer:
75

As the first step extending the segment BC until intersection with AD.
Since ∠A + ∠B = 90° we get right triangle by extending CB
Naming the segments a, b, c, d as pictured
<u>The are of (ABCD) is equal to sum of areas of two right triangles:</u>
<u>Substitute d with a-c as a = c+d, then:</u>
- Area = 1/2(ac+bc) + 1/2b(a-c) = 1/2(ac + bc + ab - bc) = 1/2(ab + ac)
- Area = 1/2(ab+ac)
<u>Applying Pythagorean to small triangle:</u>
- 10² = b² + (a-c)²
- 100 = b² + a² - 2ac + c²
<u>Applying Pythagorean to bigger triangle:</u>
- 20² = (a+b)² + c²
- 400 = a² + 2ab + b² + c²
<u>Subtracting equations we got:</u>
- 400 - 100 = a² + 2ab + b² + c² - (b² + a² - 2ac + c²)
- 300 = 2ab + 2ac
<u>This gives us the 4 times of the area which is 1/2(ab + ac), so the area is </u>
