Which is a solution to the equation?
stiks02 [169]
If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:

(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4

The correct result would be x = - 7.

The population of Miami-Dade County in Florida in 2010 was 2, 496, 435 and the land area was 1, 898 square miles. The population
Jet001 [13]

The population density of the city which is the ratio of population size and the land area is 1419 people per square mile.

  • The initial population = 2496435
  • The percentage increase in population = 7.9%

  • Land Area = 1898 mi²

<u>The population of the city on 2015 can be calculated thus</u> :

  • (1 + percent increase) × initial population

  • (1 + 0.079) × 2496435 = 2693653.365 people

<u>The population of a city is calculated using the relation</u> :

  • Population density = Population / Land Area

  • Population density = 2693653.365/1898

  • Population density = 1419.21

Therefore, the population density is 1419 people per square mile.
