Answer:
[tex]\sqrt{41}[/tex]
Step-by-step explanation:
First of all this is too easy, if you are having problems with this then I highly recommend you to ask your teacher for help
Formula -> [tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Identify which is x and which is y
-> E (1,7) F(-3,2)
|[tex]x_1[/tex]|[tex]y_1[/tex]| |[tex]x_2[/tex]|[tex]y_2[/tex]|
-> [tex]D=\sqrt{(-3-1)^2+(2-7)^2}[/tex]
-> [tex]D=\sqrt{(-4)^2+(-5)^2}[/tex]
-> [tex]D=\sqrt{16+25}[/tex]
-> [tex]D=\sqrt{41}[/tex]
