Well, there is 6 corners that doesn't touch each other. And if you add the ones that are touching each other then it has 10 corners.
X^2 - 10x + 8 =0
x^2 - 10 + (-10/2)^2 - (-10/2)^2 + 8 = 0
(x - 5)^2 - 25 + 8 = 0
(x - 5)^2 - 17 = 0
To be honest , this is the final step for this equation. It seems like there is no any suitable answer for this question..
To me , I think the best answer will be the third option.
x - 5 =0
x = 5
2x-10 = 0
2x = 10
x = 5
I guess this answer seems like legit.. So I will choose the third option.
It seems a lot like 120. 60 and 60 rounded is 60 each. 60 + 60 = 120
(sorry if i'm wrong)
