<span>–3(x + 3)^2 – 3 + 3x
</span>First, we expand the term to be squared:(x + 3)^2 = x^2 + 6x + 9So the expression becomes-3(x^2 + 6x + 9) - 3 + 3x-3x^2 - 18x - 27 - 3 + 3x-3x^2 - 15x - 30
<span />
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%
