When you’re driving and your instructor tells you to do a shoulder check, do you look directly to the right and left or behind your shoulder

i'm taking the permit test soon so i believe the answer would be to check behind your shoulder? sorry if im wrong!

Step-by-step explanation:

If you're moving the vehicle to the right, shoulder check by moving your head 90° to the right. Turn your head 90° degrees in the direction you're moving the vehicle. And, if you're moving the vehicle to the left, you shoulder check to the left by turning your head 90° to the left.

both equations and proportions are better.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
