Answer:
Square; x=2; y=1
Step-by-step explanation:
Being that the following quaderlateral has equal sides and angles equal to 90 degrees each, it would be classified as a square.
Now, knowing that they have all equal sides, you could say that
1). 5x-4=3x
as well as
2).2y+4=5y+1
Now, solve for each of the variables:
1). 5x-4=3x
(Minus 3x from both sides and add 4 to both sides)
2x=4
(Divide by 2)
x=2
2). 2y+4=5y+1
(Minus 5y from both sides and minus 4 to both sides)
-3y=-3
(Divide by -3)
y=1
Hope it helped! (:
