Answer:
The farmer would need 80 posts.
Step-by-step explanation:
If one side of the garden is 10m long, and the garden is a square, we can assume that all 4 sides will be 10m. That makes it 40m in total. Times 40×2 and you get 80.
The another way to represent the same line, for solving
will be: 
<u><em>Explanation</em></u>
Given equation of the line is: 
"Solving
" means <u>we need to get</u>
<u>alone in left side.</u> So, we will eliminate all other terms except
from the left side.
First we will <u>subtract 2x </u>from both sides. So, we will get......

Now, we will <u>divide both sides by 3</u> for getting
alone. So.....

Thus, the another way to represent the same line, for solving
will be: 
Take $438÷4=109.5 take 184-109.5=74.5. Then 74.5×4=298. The correct answer is C.
