Answer:
[tex]38[/tex]
Step-by-step explanation:
To find the answer, we can use the distance formula: [tex]d=\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
-------------------->>>>
[tex]d=\sqrt{(31-(-7))^2+(9-9)^2}[/tex]
[tex]d=\sqrt{(38)^2+(0)^2}[/tex]
[tex]d=\sqrt{1444}[/tex]
[tex]d=38[/tex]
---------------
Hope this is helpful.
We need distance between the points
Distance:-
[tex]\\ \sf\longmapsto \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\\ \sf\longmapsto \sqrt{(31+7)^2+(9-9)^2}[/tex]
[tex]\\ \sf\longmapsto \sqrt{38^2}[/tex]
[tex]\\ \sf\longmapsto 38fts[/tex]
