To find population density, it is population / area.
The population is 6688, divided by the area of 16.
6688/16 = 418
So the population density is 418 people per sq mile.
It is in simple form. There is absolutely nothing more that can be done, unless it is a joke. And math jokes are very hard to come by.
I don't think that y(y - 1)/(a + 2b) is any simpler.
Come to think of it, is that x^2 or y^2 on the top left.
I think my first answer is the best one. Nothing can be done.
1m=100cm
85 cm
400 mm=40 cm
Add up them up and you get 225 cm in total
Answer:
The equation of the line is 
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope and b is the y-intercept(the value of y when x = 0).
Perpendicular lines:
If two lines are perpendicular, the multiplication of their slopes is -1.
Line perpendicular to y = 4x + 4.
This line has slope 4, so our line will have slope:
So
Through (0, -3)
This means that 
So
Answer:
If we used the quadratic formula to solve the equation we can say:
-b = -5
b² - 4ac = 13
2a = 2
Solving the first and last equations we get b = 5 and a = 1. Substituting these values into the second equation we get:
25 - 4c = 13
Solving this we get c = 3 so the answer is x² + 5x + 3.
