Answer:
14 units
Option D is the correct option.
Step-by-step explanation:
Let the points be A and B
A ( 7 , 35 ) -----> ( x1 , y1 )
B ( 7 , 21 ) -------> ( x2 , y2 )
Now, finding the distance between these two points:
[tex] \sqrt{(x2 - x1) ^{2} + {(y2 - y1)}^{2} } [/tex]
Plug the values
[tex] = \sqrt{(7 - 7) ^{2} + {(21 - 35)}^{2} } [/tex]
[tex] = \sqrt{ {0}^{2} + {( - 14)}^{2} } [/tex]
0 raised to any positive power equals 0
[tex] = \sqrt{0 + {( - 14)}^{2} } [/tex]
When adding or subtracting 0, the quantity doesn't change
[tex] = \sqrt{ {( - 14)}^{2} } [/tex]
Reduce the index of the radical and exponent with 2
[tex] = 14 \: units[/tex]
Hope this helps...
