One point: draw the line a bit lower such that it touches the circle. A line from the center of the circle to the line will be perpendicular to it.
Two points: draw the line somewhere through the circle. There will be two intersection points.
Three points: can't be done.
A linear pair means the adjacent angles form a line...meaning they equal 180 degrees
-21x+28 is factored into:
-7(3x-4)
Answer:
1 and 1/4 liters of paint are needed for one door
Step-by-step explanation:
You can eliminate each answer choice out. For '4/5 liters' you know that if that amount was used, it wouldn't be reasonable since it would mean that the more was used for the other 3/5 door. 3 and 1.5 would be too much since it is over 2 liters. 2 liters wouldn't be logical since you paint 1 <em>and</em> 3/5 of a door and you only used 2 liters, no more or no less, basically what would you use for the other 3/5 door if this was the answer.
Hope this helps!
