Answer:
The explicit formula for a given geometric sequence is of the form
Step-by-step explanation:
Given sequence is 
Let 
To find the common ratio r:
Therefore r=-3
Therefore r=-3
Therefore common ratio is -3
Therefore given sequence is geometric sequence.
The explicit formula for a geometric sequence is 
, where common ratio is r.
From given sequence we are having r=-3
Therefore the explicit formula for a given geometric sequence is of the form 
Answer:
What's the question?
Step-by-step explanation:
The area of a shape is the amount of space it occupies
The complete statement is: First, break the irregular polygon into shapes whose area you can find using familiar formulas. The sum of these areas is the area of the polygon.
<h3>How to determine the area of an irregular polygon</h3>
An irregular polygon contains several familiar shapes.
So, the first thing to do is to break the polygon into smaller shapes
Then calculate the areas of these shapes
Lastly, add the areas of the shapes to get the area of the irregular polygon
Hence, the area of an irregular polygon is the sum of the areas of the shapes that make up the irregular polygon

Answer:
60 degrees
Step-by-step explanation:
60 degrees because all sides are equal and 180/3 is 60.
since they cost the same we can work out the price of one by dividing 60 by 5 which is 12
so if each one costs 12 and we need the price of 2 then we just do 12×2 which is 24
the answer is $24
