A. (x, y) → (x, y + 4) B. (x, y) → (x, y − 4)
C. (x, y) → (x + 4, y)
D. (x, y) → (x − 4, y)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

50- 250 is correct i did that one too

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
