the coordinates of three vertices of square ABCD are (-2 1/2, 1 1/2), B (-2 1/2, -3), and C (2, 1 1/2) when point D is placed on this square, what will the perimeter of the square be?

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

answer: the answer is d

idk what the heck he answer is, i’m just putting this here so i finish my account
