If I were solving this equation, I would put x^2-20x+(100)=(10). Since this is in standard form, you could change this into vertex form by making the equation y=(x-10)^2 -10.
I think the answer is B y= 3x-7
I think its A.Hope that helps :)
A. (3x7)+(3x4)
should be the correct one bc the other options dont get the same answer in the end
