Answer: 52
Use the pythagorean theorum to calculate WX, since it's a rhombus, all sides are equal, multiply by four, finished.
Answer:
3*3*3*3*3
Step-by-step explanation:
X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3
