Answer:
n < - 3 or n > - 2
Step-by-step explanation:
Inequalities of the type | x | > a , have solutions of the form
x < - a or x > a
Then
2n + 5 < - 1 or 2n + 5 > 1
Solve both inequalities
2n + 5 < - 1 ( subtract 5 from both sides )
2n < - 6 ( divide both sides by 2 )
n < - 3
OR
2n + 5 > 1 ( subtract 5 from both sides )
2n > - 4 ( divide both sides by 2 )
n > - 2
Solution is n < - 3 or n > - 2

Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon
![Sum\ of\ interior\ angles = (n-2)*180](https://tex.z-dn.net/?f=Sum%5C%20of%5C%20interior%5C%20angles%20%3D%20%28n-2%29%2A180)
Here n is the number of sides of polygon
In the given polygon
n = 7
So,
![Sum = (7-2)*180 = 5*180 = 900](https://tex.z-dn.net/?f=Sum%20%3D%20%287-2%29%2A180%20%3D%205%2A180%20%3D%20900)
Hence,
The sum of interior angles of given polygon is 900°
Answer:
The simplified answer would be 7m+63. You would have to solve for the variable.
Step-by-step explanation:
Answer:
a) 1790 b) 1.79
Step-by-step explanation:
a) you just add to get the perimiter 2(900) + 2(400) to get 1790
b) 1000 meters makes a kilometer so we divide by 1000 and get 1.79 for the kilometers
