2,300 meters is the answer to your question.
The correct answer is C (-20) let me know if you want to know how I got that answer
X = 29 and y = 101.
To find this, you need to set up an equation.
6x - 95 = 79. Once you solve this, x would equal 29.
Since 6x - 95 and y are on a straight line, they would have to equal 180. So you make another equation except you plug in 29 for x this time.
6(29) - 95 + y = 180. Once you solve this, y would equal 101.
(6n^2-4)+(-2n^2+9)
6n^2-4-2n^2+9
4n^2+5
Hope this helps!
