20 liters I looked up the answer and did research on how to find it.
Was that what x is equal to or is that the actual log problem? If so, what is it equal to? Typical log problems have log, a sub unit, a exponent, and a number its equal too. If its the reversed version (Sorry, i honestly don't know the mathematical term for it) it will have a base number and exponent equal to another number. Sorry i couldn't help out more!
Answer:
136 miles
Step-by-step explanation:
Distance is product of speed and time.
Given the car that moves South takes 2 hours then the speed is 55 mph
D=st
Where s is speed, t is time and D is distance covered. Substituting 2 hours for time and 55 mph for s then
Distance=2*55=110 miles
Using trigonometry
Cos 36°=110/x
X=110/cos 36°=135.967477524977 miles
Alternatively
X=110/sin 54°=135.967477524977
Rounded off, this is approximately 136 miles
steps: 1. get rid of the ( )
2. ² and
3. x and ÷
4. + and -
so:
-3(x-2)²+170
= (-3x+6)²+170
= (-3x×-3x+ 2×-3x×6 +6×6)+170
= 9x²-36x+36+170
= 9x²-36x+206
