Find all real or imaginary numbers to the equation.

1.

6x = -(19x+25)/(x+1)

Find exact and approximate solutions to each problem.

2. Boxing Match . A boxing ring in the shape of a square , 20 feet on each side . How far apart are the fighters when they are in opposite corners of the ring?

3. For 1989 and 1990 Dave Johnson had the highest decathlon score in the world . When Johnson reached a speed of 32 ft/second the pole vault runway, his height above the ground t seconds after leaving the ground was given by h =16t^2 + 32t. ( the elastiticity of the pole converts the horizontal speed into vertical speed .) Find the value of t for which his height was 12 feet.

4.Use the information from number 3 to determine how long Johnson was in the air . For how long was he more than 14 feet in the air ?
