1.) EH is a(n)_________ of the hexahedron.

In what order would we solve for n?<br> 3n - 4 = 14

Blizzard [7]

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation;

3*n-4-(14)=0

Pull out like factors :

3n - 18 = 3 • (n - 6)

Solve : 3 = 0

This equation has no solution.
A a non-zero constant never equals zero.

Solve : n-6 = 0

Add 6 to both sides of the equation :
n = 6

Please help ASAP 30 pts + brainliest to right/best answer

azamat

Answer:

Step-by-step explanation:There's nothing there to solve. But you can simplify the expression.-- The difference of two logs is the log of the quotient. log₆(25) - log₆(5) = log₆(25/5) = log₆(5) .That may be all you can do with it.If they want you to go ahead and actually find the value of log₆(5) ...I don't remember how to do that. If it was log₁₀(5) or ln(5) ,those would be easy, because they're right on your calculator.But the log to the base of (anything else other than 10 or 'e') takesan additional step, which I don't remember. brainliest pls?

If w = 12 units, x = 7 units, and y = 8 units, what is the surface area of the figure? Figure is composed of a right square pyra

bearhunter [10]

Answer:

720 sq units.

Step-by-step explanation:

Length and width of square prism, w = 12 units

Height of square prism, x = 7 units

Height of square pyramid, y = 8 units

Please have a look at the attached image.

Here 2 Surfaces will not be exposed which are base of the square pyramid and the top of the square prism i.e. 2 square surfaces will not be exposed.

Here, surface area of the composite figure will be:

<em>Surface Area of Composite Figure = Lateral surface area of Square Pyramid + Surface Area of 5 surfaces of the square prism</em>

For finding the lateral surface area of pyramid, we need to find the slant height of the pyramid.

Let slant height be $l$ units.

Using pythagoras theorem, we can find out the value of $l$ .

As per theorem:

$Hypotenuse^{2} = Base^{2} + Height^{2}\\$

$\Rightarrow l^{2} = (\dfrac{w}{2})^{2} + y^{2}\\\Rightarrow l^{2} = (\dfrac{12}{2})^{2} + 8^{2}\\\Rightarrow l^{2} = {6}^{2} + 8^{2}\\\Rightarrow l^{2} = 36+64 = 100\\\Rightarrow l = 10\ units$

Lateral surface area of square prism = 4 $\times$ Area of triangular surface

$\Rightarrow 4 \times \dfrac{1}{2}\times Base \times Slant\ Height\\\Rightarrow 4 \times \dfrac{1}{2} \times 10 \times 12\\\Rightarrow 240\ sq\ units$

Surface Area of 5 surfaces of the square prism =

$4 \times x \times w + w^2\\\Rightarrow 4 \times 12 \times 7 + 12^2\\\Rightarrow 336 +144\\\Rightarrow 480\ sq\ units$

So, total surface area of composite figure:

240 + 480 = 720 sq units.

The population of the town was 25,000 people.Then 3,200 people moved away.What was the percent of increase?

german

Answer:

-12.8%

Step-by-step explanation:

To calculate the percent decrease, we:

Find the difference between the new value and the original
Divide the number by the original
Multiply by 100 and the % symbol.

The population of the town originally had 25,000. 3,200 people moved away. This means that the new population is 21,800.

21,800-25,000=-3,200
-3,200/25,000=-0.128
-0.128(100)=-12.8%

The towns population decreased by 12.8%.
