Find the difference.
(14m+ 4) - (7m-1)

α. 21m+ 5
β. 7m + 3
c. 7m+ 5
d. 21m+ 3

Option C

The difference of (14m + 4) - (7m - 1) is 7m + 5

Solution:

Given that the expression is (14m + 4) - (7m -1)

We need to evaluate the expression and find the difference

The expression can be evaluated according to BODMAS

BODMAS represents the sequence of operations - Brackets, Order, Division, Multiplication, Addition and Subtraction.

⇒ (14m + 4) - (7m -1)

According to BODMAS, Brackets has to evaluated first.

⇒14m + 4 - 7m + 1

Now adding the like terms we get,

⇒ 7m + 5

Hence the difference of given expression is 7m + 5 Hence Option C is correct

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
