6? maybe 12 idk but its the best i could do
Yes, yes it is!
Because every point on the line of this equation is also a solution!
THis is called a linear equation!
-- The area of the long skinny piece on top is (6 x 33) = 198
-- The length of the dotted line between the top and bottom pieces is (33-21) = 12
-- The area of the bottom piece is (12 x 15) = 180
-- The area of the whole thing is (198 + 180) = 378
-- The perimeter of the whole thing is (33 + 6 + 21 + 15 + 12 + 15 + 6) = 108
(x-1)(x+1)(x-3)(x+3)
x²-y² formula
Mark brainliest please
