Question

What’s the correct answer for this?

Answer 1

Answer:

20

Step-by-step explanation:

Answer 2

Answer:

Distance between two points (x1, y1) and (x2, y2):

D = sqrt((x1 - x2)^2 + (y1 - y2)^2)

Then, distance between two points (5, 9) and (-7, -7):

D = sqrt((5 + 7)^2 + (9 + 7)^2) = sqrt(144 + 256) = sqrt(400) = 20

=> Option A is correct

Hope this helps!
