3.14(12.5) = ?
39.25

d. 39.25
Use the website desmos.com, it's an online graphing calculator. just input the formula, and then just copy the graph.
Plus the simplified equation would be:
-2x+y=-6
add 2x to both sides
y=2x-6
I hope and think it’s 12015
Because this what I did I (.89)x
And x = 13500 and I got 12015
21 because you have to have at least 1 side as 3m so the other two should be 9m to have the greatest possible length
