Answer: 2.4×10^5

Step-by-step explanation:

30×8×10^3

What is the distance between the point (−10, −2)(−10, −2) and the point (−4, −2)(−4, −2) ?

Gnoma [55]

In this case: x 1 = - 10, y 1 = - 2;
x 2 = - 4 , y 2 = - 2
The distance between the points :
$d = \sqrt{(x 2 - x 1 ) ^{2} + ( y 2 - y 1 ) ^{2} } = \\ =\sqrt{(-4+10) ^{2} +(-2+2) ^{2} } = \\ = \sqrt{6 ^{2}+0 ^{2} } = \sqrt{36}= 6$
Answer: d = 6
