Answer:
A. -2x^2-2x-2
Step-by-step explanation:
(2x^2-5x-4)-(4x^2-3x-2)
distribute the minus sign
(2x^2-5x-4)-4x^2+3x+2
2x^2-5x-4
-4x^2+3x+2
-------------------------
-2x^2 -2x-2
So 4 hours
1 hour=60 minutes
1 minute=60 seconds
1 hour=60 times 60 seconds=3600seconds
4 hours=3600 seconds times 4=14400seconds
so 8 out of 14400
8/14400=2/3600=1/1800
percent means parts out of100 so
x%=x/100
the reatios are equal to
1/1800=x/100
mulitply both sides by 100
100/1800=x
1/18=x
divide out
0.055555555=x
round
0.06%
