Consider the equation: x^2-4x+4=2x
1) Rewrite the equation by completing the square.
Your equation should look like (x+a)^2=b(x+a) or (x-c)^2=d(x−c)
2) What are the solutions to the equation?

The decibel level of sound is 50 db greater on a busy street than in a quiet room where the intensity of sound is watt/m2. the level of sound in the quiet room is db, and the intensity of sound in the busy street is watt/m2. use the formula , where is the sound level in decibels, i is the intensity of sound, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).

1. are the triangles similar and if so why? what is the value of x? show your work.
