No, because the sum of the angles of any polygon is equal to 180(n-2), where n is the numbers of its sides, and 450÷180=2.5
Hope this helped!
Y/z dosent belong on it I even think its not a number.Lol hope this helps :)
They are asking for the outcome of A and B, which means you need to include the results of both together.
The result would be {4,5,6,7,10,11,12}
Since there are no common numbers in either A or B, they would be mutually exclusive.
The answer would be the last one.
Answer: 5) r = 5, 8th term = -78,125
6) r = 5, 8th term = -312,500
7) r = 5, {1, 5, 25, 125, 625}
8) r = 5, {-4, -20, -100, -500, -2500}
<u>Step-by-step explanation:</u>
The explicit formula of a geometric sequence is: 
, where;
- n is the number of the term
- a₁ is the first term
- r is the common ratio
Answer:
-145
Step-by-step explanation:
-5-15-25-x=100
First, get all the numbers(including 100) on one side and x on the other side(make sure x is POSITIVE, not negative)
-5-15-25-100 = x
Two negatives = addition
-5 - 15 = -20
-25 - 100 = -125
Now add, 20 and 125, and keep the negative
-125 - 20 = -145
