The distance fro, (12,-5) to (-3,7) is [tex]\sqrt{369}[/tex]
First, you must set up the distance equation.
[tex]\sqrt{(-3-12)^2+(7+5)^2}[/tex]
Then, you must add like terms.
[tex]\sqrt{(-15)^2+(12)^2}[/tex]
Next, simplify exponents.
[tex]\sqrt{225+144}[/tex]
Finally, simplify the radical.
[tex]\sqrt{369}[/tex]
The radical cannot be simplified, so the answer is [tex]\sqrt{369}[/tex]
