Hey there! Hello!
So, for this problem, I don't really see an answer choice that fits along with this description?? The last one is the closest to the answer I believe it is, but still doesn't fit exactly:
Twice a number = 2n
Three more than = +3
Final equation = 2n+3
Perhaps you have a typo either in your question or your answer problem, or I'm just way too tired. Either way, I hope this helped you out, and feel free to ask me any additional questions you may have.

Answer:
<u>81920</u>
Step-by-step explanation:
Finding the common ratio (r) :
Finding the 14th term :
- a₁₄ = ar¹⁴⁻¹
- a₁₄ = ar¹³
- a₁₄ = (10)(2)¹³
- a₁₄ = (10)(8192)
- a₁₄ = <u>81920</u>
If diameter is7, the radius is 3.5m
so c=2πr
=2×3.14×3.5
=21.98m

<h2>Solving the Question</h2>
In this case, we're given the following information:
- Mother = $9
- Grandmother = $1 per mile
- Isabelle walks <em>x</em> miles, mother pledge = grandmother pledge
The mother's donation of $9 will not change <em>no matter how many miles Isabelle has walked</em>, so if both the mother's and grandmother's donations are equal, they must each owe 9$.
<h2>Answer</h2>
Each donor owes $9.
To answer this question, let us find the slope using the coordinates:
(2, 1) and (3, 4)
1 - 4 / 2 - 3
-3 / -1
3
The slope is 3, so the answer is neither, since a horizontal line has a slope of 0 and the slope of a vertical line is undefined.
