1. solve. x^2+9x+2=0 enter your answers, as exact values, in the boxes. 2. what is the solution of the equation when solved over the complex numbers? x^2+24=0

1. using the quadratic formula you get -9+/-sqrt(9^2-4*(1*2))/2*1

 this simplies to x = -9 +/- sqrt(73)/2

x = -0.22799812 and -8.77200187

2.  complex numbers have the letter i with them

 using the quadratic formula

 you get 0 +/- sqrt(0^2-4*(1*24))/2*1

x = -2i sqrt(6) and 2i sqrt(6)

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
