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:
Step-by-step explanation:
Hi
First Youre going to want to bring all the y to one side so you’re gonna add +2y to each side, on the right it cancels out so itll be 5y-4=6, next your are going to add +4 to each side on the left it cancels out now you will have 5y=10, now you are gonna divide each side by 5, so youre answer will be y=2
The scale factor's 3 since 12 and 4 can be divided by 3 and -6 and -2 can also be divided by 3.
The answer is 5:9 because 18 in half is 9 therefore 10 in half is 5
