The secant tangent theorem states that the distance from (y to the tangent point x) squared = the external segment * length of the secant.
Put in plane English
YX^2 = YV * YZ
YV = 9
YZ = 9 + 19 = 28
YX^2 = 28 * 9
yX^2 = 252
YX = sqrt(252)
YX = 15.87

CaHeK987 [17]

$\frac{3b}{b+2}+\frac{12}{b+2}=\frac{3b+12}{b+2}\\\\\\\frac{3b+12}{b+2}=\frac{3b+6+6}{b+2}=\frac{3b+6}{b+2}+\frac{6}{b+2}=\frac{3(b+2)}{b+2}+\frac{6}{b+2}=3+\frac{6}{b+2}$

Let f (x)=2x-1 ,g (x)=3x,solve g (f (x))

Zolol [24]

G(x) = 3x
g(x) = 3*( x )
g(f(x)) = 3*( f(x) ) ... every x has been replaced with f(x)
g(f(x)) = 3*( 3x ) ... replace the f(x) on the right side with 3x
g(f(x)) = (3*3)x
g(f(x)) = 9x
