Answer:
The answer is
20 units
Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(5,9) and (-7,-7)
The distance between them is
[tex]d = \sqrt{ ({5 + 7})^{2} + ( {9 + 7})^{2} } \\ = \sqrt{ {12}^{2} + {16}^{2} } \\ = \sqrt{144 + 256} \\ = \sqrt{400} [/tex]
We have the final answer as
20 units
Hope this helps you
