The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1
x² + y² = 9
x²/25 - y²/36 = 1
From (1)
x² = 9 - y²
substitute x² = 9 - y² into (2)
(9-y²) / 25 - y²/36 = 1
Therefore, the resulting equation is option C; (9-y²) / 25 - y²/36 = 1

Answer: 53
They are both right legs. Use a^2+b^2=c^2.
A= 28^2 B=45^2
A= 784 B= 2025. 2025+ 784= 2809 (radical 2809) To simplified is 53
