An octagon has 8 sides. Each side is given as 2a + 1

Perimeter = 8(2a + 1)

= 16a + 8

Answer: 16a + 8

as we all know ... an octagon has 8 corners / sides

and they told that each side is equal to 2a + 1

so we need to make an equation which will be <u>8 (2a+1) </u>

ans now we need to<em> multiply 8 with both 2a and 1 </em>

so, 8 ( 2a + 1 )

16a + 8

we cant do this further as its not "like"

so the answer is<em><u> 16a + 8 </u></em>

Anna35 [415]

Answer:

\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}} best completes this argument

Step-by-step explanation:

Circumference of circle =\pi \cdot d

Where d is the diameter of circle

We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to \frac{360^{\circ}}{n^{\circ}}

So, Number of sectors =  \frac{360^{\circ}}{n^{\circ}}

The arc length of each sector is the circumference divided by the number of sectors

\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}

Diameter d = 2r (r = radius)

\Rightarrow \frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}

Option b is true

Hence\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}} best completes this argument

Approximately how many more job openings are expected for security guards than pharmacy technicians?
Illusion [34]

Answer: c. 21,000

Step-by-step explanation:

Since, by the given diagram,

The approximate number of security guard job opening = 39,000

And, the approximate number of pharmacy technicians job opening = 18,000

Hence, the difference of the number of security guard job opening and the number of pharmacy technicians job opening = 39,000 - 18,000 = 21,000

Thus, the job openings for security guards is approximately 21000 greater than that of pharmacy technicians.

⇒  Option C is correct.
