um oki ...... -_- ahhhahahhahahah
yuhhh get into ittttttt luv
First you can take out a 3. And an x and a y. Thus, 3xy(3x+4y) is the answer.
Answer:
Reference angle of −504° = 36°
Step-by-step explanation:
The given angle is −504°
Now, −504° = 216° ( By adding 2 complete angles)
Now, as we know that
360° completes one complete rotation in anti-clockwise direction and
-360° completes one complete rotation in clockwise direction.
Hence,<u> 216° lies in the quadrant III.</u>
So, now the reference angle of any angle x in a third quadrant = x - 180°
So, the reference angle of 216° = 216° - 180° = 36°
Hence, the reference angle of −504° = 36°
3x^2 - 5x - 2
3x^2 - 6x + x - 2
3x (x - 2) + 1 (x - 2)
(3x + 1) (x - 2)
