Answer 1

Answer:

$7,2 ≈ D$

Step-by-step explanation:

We need to use the Distance Formula:

$\sqrt{(-x_{1} + x_{2})^{2} + (-y_{1} + y_{2})^{2}} = D \\ \\ \sqrt{(-5 + 9)^{2} + (2 + 4)^{2}} = D \\ \\ \sqrt{{4}^{2} + {6}^{2}} = D \\ \\ \sqrt{16 + 36} = D \\ \\ 2\sqrt{13} = D \\ \\ 7,2 ≈ D$

** Since we are talking about distance, we ONLY want the NON-NEGATIVE root.
