2x*x=2x^2
2x*-y=-2xy
3y*x=3yx
3y*-y=3
2*x=2x
2*-y=-2y
-3x*x=-3
-3x*-y=3xy
combine like terms and that is your answer
Answer:
720 mi²
Step-by-step explanation:
The map has a scale of 1 in: 30 mi, meaning that for every inch you see on the map, in the real-life location, it will measure 30 miles. So we can find the area of the park on the map and then turn it into miles using the scale:
Area of a rectangle:
![A=bh](https://tex.z-dn.net/?f=A%3Dbh)
Replace the known values:
![A=(4)(6)\\ A=24](https://tex.z-dn.net/?f=A%3D%284%29%286%29%5C%5C%20A%3D24)
The area on the map is 24 mi², we can turn it to miles using the scale by multiplying our result with 30:
![A=(24)(30)\\ A=720](https://tex.z-dn.net/?f=A%3D%2824%29%2830%29%5C%5C%20A%3D720)
And last but not least, don't forget to put the unit!
25x-25y would be the simplified form.
Hope this helped! Good luck! :)
1: 3.2kg
2: 12000ml
3: 2m
4: 70kg
5: 10l
6: 60000mm
Hope this works hehe
1 x 3.14 x 2 = 6.28 so the answer is 6.28
