Question 11 and 12 please help

Mathematics
1 answer:
Maksim231197 [3]2 years ago
7 0

Answer:

11. 10

12. 13

Step-by-step explanation:

Use the distance formula.

11.

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

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

d = \sqrt{(-3 - 3)^2 + (-4 - 4)^2}

d = \sqrt{(-6)^2 + (-8)^2}

d = \sqrt{36 + 64}

d = \sqrt{100}

d = 10

12.

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

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

d = \sqrt{(-5 - 0)^2 + (-12 - 0)^2}

d = \sqrt{(-5)^2 + (-12)^2}

d = \sqrt{25 + 144}

d = \sqrt{169}

d = 13
