<h2>3</h2>
Step-by-step explanation:
The equation of line passing through the two points is 
When substituted,the equation becomes 
which when simplified is 
The line clearly passes through origin.
The distance between two points is 
Distance between origin and
is
.
Distance between origin and
is 
Scale factor is 
So,scale factor is 
which when simplified becomes 3.
Answer:
B
Step-by-step explanation:
First you will add them all up
6+4+10+2=22
Second find the black and green amount and add them together
4+10=14
Thirdly turn this into a fraction
14/22
Lastly simplify
14/11 / 2 = 7/11
Quadrant I
405=360+45 405-360=45
405 is one complete counterclockwise rotation plus one half of an angle measuring 90 degrees counterclockwise rotation (=45)
4x²-12x²-6x+12x²-36x²-18x-16x+48x+24
-32x²+8x+24
I think that it might be 80 seconds (1 min 20 sec)
