Answer and Explanation:
The population of Atlanta grew strongly during the period from 2017 to 2019, thanks to an expansion of the technology center, revitalization of urban centers and regions that were previously undervalued, gradual investment in trade and real estate. This led to a decrease in the birth rate of the city, since people are busy in the labor market and have no plans to have children. This decrease in the birth rate has meant that the population of Atlanta has more elderly people than children, making it an aging population. In addition, the city's economic progress promotes an increase in life expectancy allowing an increase in the elderly population.
F(x) = x²-x
g(x) =1/x
1) h(x) =f(x) -g(x) = (x²-x) - (1/x) = (x³-x²)/x (x≠0) =>
2)h(x) =f(x).g(x) = (x²-x).(1/x) =x(x²-1)
3)h(x) = f(g(x)) = (1/x)²-(1/x)
Triangles, squares and hexagons are the only regular shapes which tessellate by themselves. You can have other tessellations of regular shapes if you use more than one type of shape. You can even tessellate pentagons, but they won't be regular ones.
