I think it’s B angle 3 and 7. And D 4 and 7 angles!
You have to distribute the minus sign to the second parenthesis, changing the sign of every term:
![-3y^2-8-(5y^2+1) = -3y^2-8-5y^2-1 = -8y^2-9](https://tex.z-dn.net/?f=%20-3y%5E2-8-%285y%5E2%2B1%29%20%3D%20-3y%5E2-8-5y%5E2-1%20%3D%20-8y%5E2-9%20)
I think it's 20 because 5 feet times 4 more times equals 20.
5*4=20
So 20 feet?
I think that's right, and I hope it helps :)
