(a) Find the derivative of the function f(x) = $\displaystyle {x}^{{2}}+{6}\cdot{x}+{5}$

..... Derivative of f(x): $\displaystyle {f}'{\left({x}\right)}=$

(b) When x = 5 then the slope of the tangent line is

(c) Write the EQUATION of the line tangent to the graph of f(x) when x = 5

..... The equation of the tangent line is $\displaystyle {y}=$
