Find dydx\frac { d y } { d x } if y=ln(x9(x+5) 12) y = \ln \left( x ^ { 9 } ( x + 5 ) ^ { \frac { 1 } { 2 } } \right)


A) 9(2x+5) 2x(x+5) \frac { 9 ( 2 x + 5 ) } { 2 x ( x + 5 ) }
B) 19x+902x(x+5) \frac { 19 x + 90 } { 2 x ( x + 5 ) }
C) 9(2x+10) x(x+5) \frac { 9 ( 2 x + 10 ) } { x ( x + 5 ) }
D) 19x+45x(x+5) \frac { 19 x + 45 } { x ( x + 5 ) }
E) 19x+18x(x+5) \frac { 19 x + 18 } { x ( x + 5 ) }
