Answer:

Step-by-step explanation:
The formula is given as:

We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:

To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables:

Putting v to left side (convention), we finally have:

Answer:
Step-by-step explanation:
so you will move constant to the right side and change the sign. 72x=223-7
then you will subtract the numbers 72x=223-7 and that will give you 72=216
then you will divide both sides by 72 and that will give you
- x=3 .
The answer is 12 good luck;)
