Answer:

10 square units.

Step-by-step explanation:

Area of Polygon C = 40 square units.

Scale factor used in obtaining polygon D = \dfrac12

To obtain the area of the new polygon, we multiply the area of the polygon from which it was derived by the square of the scale factor.

Therefore:

Area of Polygon D

=40 \times (\frac12)^2\\\\=40 \times \frac14\\\\=10$ square units

The area of polygon D is 10 square units.

WILL GIVE BRAINLIEST! Find k so that (5, k) is equidistant from (–1, 2) and (3, 0).
pochemuha

Answer:

9

Step-by-step explanation:

So first I created 2 distance forumlas and set them equal to each other

\sqrt{(5+1)^2+(k-2)^2} =\sqrt{(5-3)^2+(k)^2}

then I simplified them

(5+1)^2+(k-2)^2 =(5-3)^2+(k)^2\\

36 + k^2 - 4k +4 = k^2 + 4

-4k + 36 = 0\\

4k = 36

k = 9

when k = 9, the two distances are equal
