For this equation, we can simply divide the box's total (124) by 4 servings. 124/4 = 31. So, there is 31 crackers per serving.

<u>Explanation</u>
(2m)/(2m+3)-(2m)/(2m-3)=1
Simplifying the left hand first 
(2m)/(2m+3)-(2m)/(2m-3) = {2m(2m-3) - 2m(2m+3)}/(4m²-9)
                                         (4m²-6m-4m²-6m)/(4m²-9)
                                          = (-12m) / (4m²-9)
Now this equet to 1
(-12m) / (4m²-9) = 1
-12m =  4m²-9
4m²+ 12m -9 =0 ⇒⇒⇒ This is a quadratic equation that has 2 real solutions.
4m²+ 12m -9 =0
m² + 3m + (3/2)²= 9/4 + 9/4
(m + 3/2)² = 18/4
m = √18/2 - 3/2                or m = -√18/2 - 3/2
     = 0.621                                       = -3.621
So we can say that the equation has NO extraneous solutions.

Answer:
C. The electric car is not moving at 0 seconds and 12 seconds.
Step-by-step explanation:
Given:
The table given is:
x   0   2    4     6      8      10      12  
y   0   45  72   81    72     45     0
From the above table, we observe that the car starts from rest and its speed increases from 0 to 6 seconds, the maximum speed being 81 mph.
After 6 seconds, the speed of the car goes on decreasing till it stops at time equal to 12 seconds.
So, the speed of the car at the start when  is 0 mph as it is at rest at that time.
 is 0 mph as it is at rest at that time.
Also, when the time is  , the car has come to a stop and thus its speed has reduced to 0 mph again. So, the car is not moving after 12 seconds.
, the car has come to a stop and thus its speed has reduced to 0 mph again. So, the car is not moving after 12 seconds.
From the above conclusion, we can say that only option C is correct.
The electric car is not moving at 0 seconds and 12 seconds.
