Answer:
D. √((2 +4)² +(5 -8)²)
Step-by-step explanation:
The distance is found using the formula ...
d = √((x1 -x2)² +(y1 -y2)²)
Selection D has this formula properly filled in with the values ...
(x1, y1) = (2, 5)
(x2, y2) = (-4, 8)
Answer: A, C, and E! I just took this on Khan Academy! Please mark me brainliest because it it correct!
Answer: 
Step-by-step explanation:





Answer:
Question 9: False
Question 10: False
Step-by-step explanation:
The third side is always greater than the other two sides.
<u>Question 9</u>
a = 6, b = 6, c = 5
Since the third side is the smallest, it would not create a triangle.
<u>Question 10</u>
a = 7, b = 2, c = 5
Since the third side is the smallest, it would not create a triangle.
