Answer: -10x (5x^3 - 8x^2 - 3x - 9) is the factored solution.
(12)2x=32
2x= 32/12
2x=8/3
I apologize I'm not sure where they get the 5. So I'm very interested in this answer as well.
My guess is (C
that could be the total number
Steve ran 11 miles
let the distance Steve ran be x
Then distance Kevin ran is x + 4 ( 4 miles more than Steve )
x + x + 4 = 26 ( the sum of their distance is 26 )
2x + 4 = 26 ( subtract 4 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Steve ran 11 mies and Kevin ran 11 + 4 = 15 miles
check 11 + 15 = 26
