The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.

Graph the equation by plotting point x=2

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
