Identify the area of a regular hexagon with side length 14 in. rounded to the nearest tenth.

kakasveta [241]

$\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}ns^2\ cot\left( \frac{180}{n} \right)\qquad 
\begin{cases}
s=\textit{length of a side}\\
n=\textit{number of sides}\\
\frac{180}{n}=\textit{angle in degrees}\\
----------\\
s=14\\
n=6\leftarrow hexagon
\end{cases}
\\\\\\
A=\cfrac{1}{4}\cdot 6\cdot 14^2\cdot cot\left( \frac{180}{6} \right)$

Can you explain how to do this?

Hi there! The answer is x = 1

Let's solve this problem step by step!
$8(10) {}^{2x} = 800$

First divide both sides of the equation by 8.
$10 {}^{2x} = 100$

Now rewrite 100 as a power of 10.
$10 {}^{2x} = 10 {}^{2}$

Now we can use the following rule, which basically means that two different exponents of the same base must be the same
${g}^{a} = {g}^{b} \\ a = b$

We now get this.
$2x = 2$

Finally divide both sides by 2.
$x = 1$

~ Hope this helps you!

negative 1 times the sum of twice a number and 3 is equal to two times the difference of -4 times the number and 3. What is the

zaharov [31]

Answer:

1.5

Step-by-step explanation:

Let the number be denoted as "a"

-1 (2a + 3) = 2 (-4a + 3)

-2a - 3 = -8a + 6

-2a + 8a = 6 + 3

6a = 9
