Answer:
B
Step-by-step explanation:
I would use the Pythagorean theorem to solve distances between 2 points, and this case is no exception.
We need to find the positive difference in their x coordinates and y coordinates.
The difference in x coordinates: 7
The difference in y coordinates: 8
Now we can use the Pythagorean theorem:
7^2+8^2 = x^2
49+64 = x^2
113 = x^2
x = sqrt(113)
Therefore, the answer is B.
