2x^2y^2 - 7xy + 5y^2 + 8xy - 3y^2 + x^2y^2 + 4y^2
3x^2y^2 - 7xy + 5y^2 + 8xy -3y^2 + 4y^2
3x^2y^2 + xy + 5y^2 - 3y^2 + 4y^2
3x^2y^2 + xy +6y^2
Answer:1.04%
Step-by-step explanation:
12.5/12 = 1.04166667
when we round this to the nearest hundredth its 1.04%
The number would be 826. 826 rounded to the nearest ten would be 830 because when you have a number at the end that is 5 or higher, it would round up.
The answer is 256 hope this helps :)
