Step-by-step explanation
Here ...I'm not too sure about the question as you have written
P = 2 ( 1 + 6 ) and ask to solve for L ...
.So I guess the question you have written is wrong .. ...and I guess there should be L in the place of 1.
...So let me correct the question....
P = 2 ( l + 6 )
P = 2l + 12
P - 2l = 12
- 2l = 12 - P
- 2l = - P + 12
Change the sign of both side of the equation...
2l = P + 12
divide both side by the same number...
L = ( P + 12 ) ÷ 2
Calculate the product of rational numbers...
1. 1/2
2.2/3
3. 1
4. 1/3
5. 2/7
6. 1/4
7. 4/3
8. 3/2
<h3>How to evaluate the value</h3>
To find 2x of the vale of x, we have to multiply the value of 'x' by 2
1. x = 1/4
⇒ 
⇒
2. x = 1/3
⇒
3. x = 1/2
⇒ 
⇒ 
4. x= 1/6
⇒ 
⇒ 
5. x = 1/ 7
⇒ 
6. x = 1/8
⇒ 
⇒ 
7. x = 2/3
⇒ 
8. x = 3/4
⇒

Answer:
Step-by-step explanation:
The sum of the interior angles of an n gon is found by using the following formula.
(n-2)*180 = sum of the interior angles.
(n - 2) * 180 = 3960 Divide by 180
(n - 2) 180/180 = 3960/180 Show the division
n - 2 = 22 Add 2 to both sides.
n -2+2=22+2 Combine
n = 24
======================================
To find the size of each angle, use
(n - 2)*180/n
(24 - 2)*180/24
22 * 180/24
3960/24 = 165
===========
another way
===========
You already know there are 24 sides. You are given the sum of the interior angles as 3960
All you really need to do is 3960/24 = 165
