The answer choices are A) Triangle ABC is translated 14 units to the right and 2 units down

B) Triangle ABC is reflected over the x-axis and translated 2 units down

C) Triangle ABC is translated 14 units to the right and a 90 degree clockwise rotation about the origin

D) Triangle ABC is reflected over the y-axis and translated 4 units right

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

apex says the answer is true

that would be a prism, if not right, feel free to correct me
