What is the distance between (-6, 2) and (8, <br> 10) on a coordinate grid?
Vinil7 [7]

Answer:

2√65

Step-by-step explanation:

The difference in the x-coordinates of the two points is 8-(-6) = 14.

The difference in the y-coordinates of the two points is 10-2 = 8.

These distances can be considered to be the lengths of the legs of a right triangle whose hypotenuse is the line segment between the given points. Then the distance between the points is given by the Pythagorean Theorem as ...

... d = √(14² +8²) = √260 = 2√65 ≈ 16.1245

PLEASE HELP!!!!!!!!!!!
devlian [24]

Answer:

I think it's 18

Step-by-step explanation:

because I'm looking at 12/8 to be a ratio, that means that the size of the bigger figure had decreased by 12/8 or 1.5

then I divided the 27 by 1.5 to get the area of the small one which was 18.
