The angles 1 and 2 are right angles.
As stated in the question line l is perpendicular to line m and perpendicular lines create right angles
Hope this helps :)
This is a question of probability.
Probability of picking any color= number of tiles with that color/total number of tiles
Total=45+25+30=100
P(red tile)=(45/100)x60=0.45x60=27
P(blue tile)=(25/100)x60=0.25x60=15
P(green tiles)=(30/100)x60=0.3x60=18
17
it's 17+(-7)=10
i hope that answers your problem
I'm guessing you want to know how much is in one case,
36/3 = 12
Multiply by distribution:
6x³ - 6x² - 12x - 18x² + 18x + 36
Combine like terms:
6x³ - 24x² + 6x + 36
The correct choice is the first choice.
