Answer:
<h2>P = 48</h2><h2>A = 144 </h2>
Step-by-step explanation:
The formula of regular polygon with <em>n</em> sides of length <em>b</em> and apothem <em>a</em>:

We have:
n = 6
b = 8
a = 6
Substitute:

The perimeter:

h = 6
Work Shown:
4h + 6 = 30
1. 4h + 6 -6 = 30 - 6 ---> 4h = 24
2. 4h /4= 24/4 ---> 6
h = 6

3x + 2* (x - 1) - 4 =
3x + 2* x + 2* (-1 ) - 4 =
3x + 2x - 2 - 4 =

</span>
3x + 2x - 2 - 4 =
5x - 6
Answer B
Hi there!
Simplify th' Eqⁿ :-
5 (x - 10) = 30 - 15x
⇒ 5x - 50 = 30 - 15x
⇒ 5x + 15x = 30 + 50
⇒ 20x = 80
⇒ x =

= 4
Hence,
The required answer is. x = 4
