N-1(-1/2) is the formula because the sequence is taking half of the previous number and changing its sign
7x + 5 = 8x - 25
- 5 = -8x -5
-------------------------------
7x - 8x = - 5 - 25
-1x = - 30
----- -------
-1 -1
x = 30
<span>y=axb^x.
when x>0 and not equal to 0</span>
Answer:
3,960 degrees
Step-by-step explanation:
The sum of interior angles of a polygon can be found using:
S= (n - 2)*180
where s is the sum, and n is the number of sides.
This is a 24 sided polygon. Therefore, substitute 24 in for n (number of sides).
S = (24 - 2)*180
Subtract inside the parentheses first
S= (22)*180
Multiply 22 and 180
S=3960
The sum of the interior angles of a 24 sided polygon is 3,960 degrees
