2b+6b

8b

Step-by-step explanation:

if you add 2+6 you will get 8 and because 2b and 6b are common factors they add together to get 8b. Hope I helped!!

8b

Collect like terms by adding their coefficients (2+6)b.

Then add the numbers. (2+6)b=8b

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
