Geometric sequence is a sequence of numbers that have a common ratio between them.
For a regular n-agon with side length "s" and apothem "h", the area will be
.. A = n*(1/2)*s*h
Your area is
.. A = 10*(1/2)*(3.25 m)*(5 m) ≈ 81.3 m^2
The mode is whatever number that repeats itself the most, which would be 3 in this case. To find the range you would find the difference between the highest number and the lowest number. The highest number is 8 and the lowest is 1 so 8-1=7. The range is 7.
So first, you want to open the parenthesis here.
So, to do that, first look at the symbol before the parenthesis.
In this case it's a -.
So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)
So,
9x - 2x - 8
Or simplified,
7x - 8
The ratio of yellow to total is 2 to 8, or 1:4 if you divide both by 2. So the answer is B.
