<h3>
Answer: Choice A</h3>
The first line shown in choice A is 
which means "the first term is -2"
The next line in choice A means "the nth term (
) is found by multiplying the prior term (
) by 8". Put another way: multiply each term by 8 to get the next term.
first term = -2
second term = 8*(first term) = 8*(-2) = -16
third term = 8*(second term) = 8*(-16) = -128
fourth term = 8*(third term) = 8*(-128) = -1024
and so on.
Answer: The answer is C or 13 units
How?: by a method called rise over run
the rise is at the y axis and the run is at x axis
*COUNT VERY CAREFULLY*
if you count right you should get 6 as a rise and 7 for run
6+7= 13
1st angle = 2 * 2nd angle
3rd angle = 2nd angle + 80
1st angle = 2x
2nd angle = x
3rd angle = 80 + x
2x + x + 80 + x = 180
4x = 100
x = 25
1st angle = 50
2nd angle = 25
3rd angle = 105
3.1 as a decimal. And it as a mixed number wait a sec.......3 1/10
Hope I could help! :)
X+8 because ur adding 8 to a number (x)
