Answer:
2x+30
Step-by-step explanation:
The formula for perimeter is
P = 2(l+w)
= 2(2/3 x+10 + 1/3 x+5)
= 2(2/3 x + 1/3 x+10+5)
= 2 (x+15)
Distribute
2x+30
44.25 - 2.25 = 42.
42/3.50 = 12
12 + 1 = 13 miles

Answer:
24
Step-by-step explanation:
You need to plug in 3 for all of the x-values
That looks like 2(3)^2 + 5(3) - 9
Then if you simplify it is 2(9) + 15 - 9
Then simplify one last time and you get a final answer of 24
