Answer:the perimeter of the regular pentagon is 5x + 20
Step-by-step explanation:
The perimeter of a plane figure is the distance around the plane figure. The pentagon is a plane figure. It has 5 sides. Since it is a regular Pentagon, it means that all the sides are equal.
From the information given, the length of each side of the regular Pentagon is x + 4
The perimeter of the regular Pentagon would be 5 times the length of each side. It becomes
5(x + 4) = 5x + 20

Answer:
Arithmetic 
An = A[n - 1] + 3/5
An = 3/5[n]
Step-by-step explanation:
Number of days = 5
Number of chocolate = 3
Computation:
Recursive:
Number of chocolate eat per day = 3/5
So,
First term a1 = 3/5
So,
An = A[n - 1] + 3/5
Explicit:
An = 3/5 + 3/5[n-1]
An = 3/5[n]

The 5 th term of the given expression is 330 .
.
Step-by-step explanation:
Given,

To find the 5th term of the given expression.
Formula
In a binomial series  , the r th term is = nC(r-1)
, the r th term is = nC(r-1)  , where,
, where,
nC(r-1) = 
Now, 
Putting, n=11, r = r, a=6x and b=6y we get,
5 th term = 11C4
= 

= 

= 330
Here is the answer.
