Answer:
What is the question? I could help
the correct answer is c
x squared over 16 minus y squared over 25 equals 1
Step-by-step explanation:
x²/4² - y²/5² = 1
x²/16 - y²/25 = 1
112/17.92 = x, y = 112 + x
You have to get x first, then plug in to next equation.
-20 or +4
(x+20)*(x-4)=0
x+20=0 or x-4=0
X= -20 or +4
