3(x+6)= -3.68

Find x, I think I know how but I’m not really sure

x = - 7.23

Step-by-step explanation:

3(x+6)= -3.68               Start with the breackets.

3x + 18 = - 3.69            Subtract 18 from both sides

3x = - 3.69 - 18

3x = -21.69                   Divide by 3

x = - 21.69/3

x = -7.23

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
