Answer 1

If A(–6, 7) and B(–1, –5) are two given points then the distance 2AB is 26.

Explanation:

Use the distance formula `d = sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2)`. 

For A(–6, 7) and B(–1, –5), 

`AB = sqrt((-1 - (-6))^2 + (-5 - 7)^2)` 

= `sqrt(5^2 + (-12)^2)` 

= `sqrt(169)`

= 13

Therefore, 2AB = 2 × 13 = 26.
