B = 12 * 5 = 60
60 is the answer
The equation of the tangent line is 
To find the tangent to the hyperbola
at (x₀, y₀), we differentiate the equation implicitly to find the equation of the tangent at (x₀, y₀).
So, 
So, at (x₀, y₀)

So, the equation of the tangent line is gotten from the standard equation of a line in point-slope form
So, 
So, the equation of the tangent line is
