Triangle ABC is shown on the graph What are the
coordinates of the image of point B after the triangle is
rotated 270° about the origin?
(4,2)
(2, 4)
-4,-2)
(-2,-4

i honestly dont know

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
