Question

Need help, pls and ty❤️❤️

Answer 1

Option D:

$d=\sqrt{(19+1)^2+(20+1)^2}$

Explanation:

Given data:

The points are (–1, –1) and (19, 20).

To find the distance between two points:

$x_1=-1, y_1=-1, x_2=19, y_2=20$

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$d=\sqrt{(19-(-1))^2+(20-(-1))^2}$

$d=\sqrt{(19+1)^2+(20+1)^2}$

Hence option D is the correct answer.
