Follow the order of PEMDAS:
You would multiply 10x10 first. That would give you 100
Then you would add 100+10. That would give you 110
Your answer would be 110 :)
120 * .08= 9.6
120 - 9.6= 110.4
When it's x²/a² - y²/b²=1 it's the one with zeros on the x axis, at x=±a, y=0.
Here the zeros are at (±5,0) so that's the first page, second graph.
