The answer would be x=12 y=20
Answer:
option-B
Step-by-step explanation:
We can rewrite left side into right side form
![(x^2+y^2)^2=(x^2+y^2)(x^2+y^2)](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3D%28x%5E2%2By%5E2%29%28x%5E2%2By%5E2%29)
we can expand it
![(x^2+y^2)^2=x^4+x^2y^2+x^2y^2+y^4](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3Dx%5E4%2Bx%5E2y%5E2%2Bx%5E2y%5E2%2By%5E4)
![(x^2+y^2)^2=x^4+y^4+2x^2y^2](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3Dx%5E4%2By%5E4%2B2x%5E2y%5E2)
we can add and subtract 2x^2y^2
![(x^2+y^2)^2=x^4+y^4+2x^2y^2+2x^2y^2-2x^2y^2](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3Dx%5E4%2By%5E4%2B2x%5E2y%5E2%2B2x%5E2y%5E2-2x%5E2y%5E2)
![(x^2+y^2)^2=x^4-2x^2y^2+y^4+2x^2y^2+2x^2y^2](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3Dx%5E4-2x%5E2y%5E2%2By%5E4%2B2x%5E2y%5E2%2B2x%5E2y%5E2)
![(x^2+y^2)^2=x^4-2x^2y^2+y^4+4x^2y^2](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3Dx%5E4-2x%5E2y%5E2%2By%5E4%2B4x%5E2y%5E2)
![(x^2+y^2)^2=x^4-2x^2y^2+y^4+(2xy)^2](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3Dx%5E4-2x%5E2y%5E2%2By%5E4%2B%282xy%29%5E2)
![(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%5E2%3D%28x%5E2-y%5E2%29%5E2%2B%282xy%29%5E2)
D: neither
If you plug in x and y’s and multiply them neither of them will equal -5
1. 9.5x + 1.5
2. 9x + 36
3. 4.8x + 2
4. 22x + 2
