Answer:
b) 4x + 3y
Explanation:
add all equations (perimeter = side + side + side)
P= 5x-3y + x+4y -2x+2y
combine like terms
5x + x - 2x = 4x and -3y + 4y + 2y = 3y
P = 4x + 3y
the answer would be B: 4x=3y
this is perimeter which means that you add the side lengths all together.
5x-3y+x+4y-2x+2y
then you just add the like terms
