3 quarters, and two thirds of a quarter so It's [3 2/3]
Do you have to find the area or perimeter?
Remember
(x^m)(x^n)=x^(m+n)
and difference of 2 perfect squres
(a²-b²)=(a-b)(a+b)
and sum or difference of 2 perfect cubes
so
(x^3)(x^3)(x^3)=x^(3+3+3)=x^9
so
x^9=3*3*x^3
x^9=9x^3
minus 9x^3 both sides
0=x^9-9x^3
factor
0=(x^3)(x^6-9)
factor difference of 2 perfect squraes
0=(x^3)(x^3-3)(x^3+3)
factor differnce or sum of 2 perfect cubes (force 3 into (∛3)³)
0=(x³)(x-∛3)(x²+x∛3+∛9)(x+∛3)(x²-x∛3+∛9)
set each to zero
x³=0
x=0
x-∛3=0
x=∛3
x²+x∛3+∛9=0 has no solution
x+∛3=0
x=-∛3
x²-x∛3+∛9=0 has no solution
so the solutions are
x=-∛3, 0, ∛3
The answer is 1, I would explain it but it’s a lot to type onto here.
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%
<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.
