Answer:
Step-by-step explanation:
If 
then angle 
is in the III quadrant.
Since 
then ![x=240^{\circ}\ [180^{\circ}+60^{\circ}]](https://tex.z-dn.net/?f=x%3D240%5E%7B%5Ccirc%7D%5C%20%5B180%5E%7B%5Ccirc%7D%2B60%5E%7B%5Ccirc%7D%5D)
(we get angle in the III quadrant)
Consider 
If 
then
Answer:
550 should be correct
Step-by-step explanation:
do 22 times 25
$x^2(x+1)+2(x+1)=(x^2+2)(x+1)$
6x-18
you pretty much h just multiply both the first part of the parentheses by the number outside, then the second :)
Answer:
You will need 50.54 liters of gas.
Step-by-step explanation:
This question is solved by proportions.
495km trip:
The gas efficiency is given in miles per gallon, so we need to find the number of miles traveled.
Each km has 0.6214 mi, so 495 km will be 495*0.6214 = 307.593mi.
Number of gallons:
23.0 mi/gal.
So for 307.593mi, the number of gallons is 307.593/23 = 13.37 gallons.
How many liters?
Each gallon has 3.78 liters.
So 13.37 gallons will have 13.37*3.78 = 50.54 liters.
