First, convert 7 kilometers to meters, which is 7000 meters.
Add that to 400, and now you he ran 7400 meters.
Now convert 1.6 kilometers to meters, which is 1600 meters.
Add that to 7400, and the total is 9000 meters.
Hope this helped!
3y^2 and -3/4y^2
5x and 2/3x
12x^2
293/12 is 24 and a lot of numbers. I think it is 24.4166667.
The answer will be (2) 0 and 9
X^2(x-9)
X=0, and 9
