The answer is $31.87.
7.29 x 3 = 21.87
5 x 2 = 10
10 + 21.87 = 31.87
Answer: Our required answer will be
![11x^2y^3-4xy^2](https://tex.z-dn.net/?f=11x%5E2y%5E3-4xy%5E2)
Step-by-step explanation:
Since we have given that
![(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)](https://tex.z-dn.net/?f=%284x%5Ey%5E3%2B2xy%5E2-2y%29-%28-7x%5E2y%5E3%2B6xy%5E2-2y%29)
We need to get the difference:
1) We first open the second bracket and make appropriate change in signs :
![4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y](https://tex.z-dn.net/?f=4x%5Ey%5E3%2B2xy%5E2-2y%2B7x%5E2y%5E3-6xy%5E2%2B2y)
2) Gather the like terms together :
![4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2](https://tex.z-dn.net/?f=4x%5E2y%5E3%2B2xy%5E2-2y%2B7x%5E2y%5E3-6xy%5E2%2B2y%5C%5C%5C%5C%3D4x%5E2y%5E3%2B7x%5E2y%5E3%2B2xy%5E2-6xy%5E2-2y%2B2y%5C%5C%5C%5C%3D11x%5E2y%5E3-4xy%5E2)
Hence, our required answer will be
![11x^2y^3-4xy^2](https://tex.z-dn.net/?f=11x%5E2y%5E3-4xy%5E2)
