Question

Use the following to determine the distance A (13,7) B (-9,4)

Answer 1

Hers is the formula for your question \[\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}\]
\[\sqrt{9+484}\]
21.2 is answer

Answer 2

1) 5
2) √493
3) √137
4) √112

Answer 3

Sorry answer is \[\sqrt{493}\]

Answer 4

\[\sqrt{(x2-x1)^2 + (y2-y1)^2}\] = \[\sqrt{(22^2 + 3^2)}\] = \[\sqrt{484+9}\] = \[\sqrt{493}\]
