Answer:
x + 10 = x² + 1
(third option listed)
Step-by-step explanation:
assuming that you meant: 
, because otherwise there would be no equivalent relationships,
(goal: isolate x on one side of the equation whilst having x on the other side of the equation also, like the equation in the question)*
x + 10 = x² + 1
-1 -1
x + 10 - 1 = x²
[find √ of both sides to isolate x]
(equation in problem)
{note: there's no reason to not simplify the equation to 
, but the question leaves the equation that way, so I didn't simplify it either}
*I used this goal to decide which equations seemed about right, and then trying to test things out in my head
I’m sorry I can’t help you without a picture if you could add a picture please I can answer this for you ツ message me back when you do!
C because the proportions are equal and multiplied by 4/4
I think it’s B because you have to find probability
But I’m not sure
