Perform the indicated operation 5/2x+3y divided by 10/4x^2-9y^2

Step-by-step explanation:

Dividing by a fraction means multiplying by the reciprocal. So we can write the problem as:

We can simplify    into    by using the formula  

Now we can write:

We can cancel out (2x+3y) and also reduce "5" and 10". Thus we have:

This is the simplified form.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
