Answer:
x = -X OR x = 0
Step-by-step explanation:
I don't know if the capital 'X' was a different variable, so I did both calculations.
2(x - 3) + 9 = 3(x + 1) + X
= 2x - 6 + 9 = 3x + 3 + X
= 2x + 3 = X + 3x + 3
= -x = X
= x = -X
2(x - 3) + 9 = 3(x + 1) + x
= 2x - 6 + 9 = 3x + 3 + x
= 2x + 3 = 4x + 3
= -2x = 0
= x = 0
The population density in the United States is D = 92.1 people/mi^2
<h3>

How to get the population density?</h3>
To get the population density, we need to take the quotient between the total number of people and the area.
In this case, we know that the total population is 325.7 million, and the area of the United States is 3,535,932 mi^2
Then the population density:
D = (325.7 million)/( 3,535,932 mi^2) = 9.21*10⁻⁵ million/mi^2
And we know that 1 million = 1,000,000 = 1*10⁶
Then:
9.21*10⁻⁵ million/mi^2 = 9.21*10¹ people/mi^2 = 92.1 people/mi^2
This means that in each square mile in the United States, there are around 92.1 people.

Answer:
D. 340 square inches
Step-by-step explanation:
Side length translates to 1 side of the square, so you do 10 x 10 to find the area of the square.
10 x 10 = 100
The triangle one isn't much more difficult. The formula for finding the area of a triangle is bh1/2
So:
10 x 12 = 120/2=60
From there just multiply the result by 4- the amount of triangles on the square pyramid, and you'll get your answer.
60
x 4
240 + 100 = 340 square inches

If it's // to y-axis that means it never intersects with y-axis . Since it passes through (3,2) means that x=3. This is the answer x=3
