Answer:
The distance between the two points is 
Step-by-step explanation:
In order to find the distance between two coordinate pairs, we can use the distance formula:

Our coordinate pairs need to be labeled accordingly, so we can use this naming system:

This assigns a name to our points:
Therefore, we can plug these into the formula and solve:

Therefore, the distance between the two points is
.
Answer:
Step-by-step explanation:
Since they have the same base as 2, by the rule of a^m / a^n = a^m-n.
So 2^7 / 2^3 = 2^ 7-3 = 2^4 = 16
6 times because 6•7=42 so it must be 6 because 7•7=49
Good luck!!
I believe the right answer is B!
