The country with the highest population density is Romania. The country with the highest population density is U.S.

Population density is the population per square km.

Population density = population / area

U.S. = 272,648,000 / 9,364,520 = 29.12

Romania = 22,609,000 / 237,391 = 95.24

Ghana = 18,339,000 / 237,533 = 77.21

The country with the highest population density is Romania. This is because Romania has the highest population density. The country with the highest population density is U.S.

Answer:

Step-by-step explanation:

First distribute the 2x to get:

4x² + 10x

Then distribute the -5 to get:

-10x - 25

Then combine

4x² + 10x - 10x - 25

The 10x's will cancel leaving you:

4x² - 25

If f x is a linear function, f(-1)=3, and f(1)=5, find an equation for f(x)

BartSMP [9]

The equation of f(x) is f(x) = x + 4

<h3>How to determine the equation?</h3>

The given parameters are

f(-1) = 3 and f(1) = 5

Start by calculating the slope (m) using:

$m = \frac{f(1) - f(-1)}{1 - -1}$

This gives

$m = \frac{5 - 3}{1 + 1}$

Evaluate

m = 1

The equation is then calculated as;

f(x) = m(x - x1) + f(-1)

This gives

f(x) = 1(x + 1) + 3

Expand

f(x) = x + 4

Hence, the equation of f(x) is f(x) = x + 4
