Question

Question 11 and 12 please help

Answer 1

11. 10

12. 13

Explanation:

Use the distance formula.

11.

(3, 4) and (-3, -4)

`d = √((x_2 - x_1)^2 + (y_2 - y_1)^2)`

`d = √((-3 - 3)^2 + (-4 - 4)^2)`

`d = √((-6)^2 + (-8)^2)`

`d = √(36 + 64)`

`d = √(100)`

`d = 10`

12.

(0, 0) and (-5, -12)

`d = √((x_2 - x_1)^2 + (y_2 - y_1)^2)`

`d = √((-5 - 0)^2 + (-12 - 0)^2)`

`d = √((-5)^2 + (-12)^2)`

`d = √(25 + 144)`

`d = √(169)`

`d = 13`
