Answer:

AB = √((-1 - 6)² + (-2 - 12)²)

= √((-7)² + (-14)²)

= √(49 + 196)

= √245

The correct answer is A.

Answer:

A

Explanation:

calculate the distance d using the distance formula

d =
\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }

with (x₁, y₁ ) = A (- 1, - 2 ) and (x₂, y₂ ) = B (6, 12 )

substitute these values into the formula for d

d =
√((6-(-1))^2+(12-(-2))^2)

=
√((6+1)^2+(12+2)^2)

=
√(7^2+14^2)

=
√(49+196)

=
√(245)
