9 years * 5% = 45%
300,000 * 45 = 13,500,000
13,500,000 / 100 = 135,000 people
300,000 + 135,000 = 435,000 people after 9 years

-3/2

Step-by-step explanation:

Let x = the integer:

2x^2 - 18 = 9x

2x^2 - 9x - 18 = 0

Now either factor that or use the quadratic formula if you're lazy like me.

x = -3/2 and 6, so x must be 6 because it has to be an integer.
