Answer:
D. y=x2+6x+1 :) hope this helps
One car 40 miles /gallon
other car 30 miles/gallon
..
Total miles = 165
gas used = 45 gallons
...
let first car drive x miles
second car drive y miles
..
x/40 + y/30 = 45
(30x+40y)/30*40 = 45
30x+40y = 45*40*30
30x+40y=54,000
(350x2=700) + (125x2=250) 700+250=950 so the perimeter is 950 meters long I hope this helps!
