Answer:
x = 15.81
Step-by-step explanation:
horizontal leg of triangle = 15
vertical leg of triangle = 9 - 4 = 5
using the Pythagorean theorem:
x² = 15² + 5² = 225 + 25 = 250
x = √250 = 15.81

Simplify the following:
x/((x - 2) (x + 9) (3 x - 6))
Factor 3 out of 3 x - 6:
x/(3 (x - 2) (x - 2) (x + 9))
Combine powers. x/((x - 2) (x + 9)×3 (x - 2)) = (x (x - 2)^(-1 - 1))/((x + 9)×3):
(x (x - 2)^(-1 - 1))/(3 (x + 9))
-1 - 1 = -2:
Answer: (x (x - 2)^(-2))/(3 (x + 9))
