16 - x = 4
16 - 12 = 4
x = 12
Answer:
Yes, the average speed for the entire trip from A to C is equal to 
Step-by-step explanation:
The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time. For the special case of straight line motion in the x direction, the average velocity takes the form:

If the beginning and ending velocities for the motion are known, and the acceleration is constant, the average velocity can also be expressed as:

We Know that:

Replacing the values:

Figure A: 5•3=15
Figure B: 3•6=18
Figure C: 4•4=16
Figure D: 4•3=12
Figure B has the largest perimeter
The Answer Is =4 :) Hope it Helps
That’s easy. To turn 5/2 into 10/4 you multiply by 2. :D Hope this helps!
