It is the same as 1/7*1/6. So the answer is 1/42
Answer:
x+y=15
Step-by-step explanation:
Given equation of 
Differentiating both side 

It passes through the point (12,3) so

So equation of tangent passing through (12,3) is
as 
So x+y =15 will be the equation of tangent which passes though the point (12,3)
13 + 6/6
13 + 1
14
The answer is 14.
