Which of the following is equivalent to the expression (4x + 7)(x - 8)?
Answer for points and brainliest

Step-by-step explanation:

I'm not sure what your choices are, but I am assuming to need to simplify.

Here is how you do it:

(4x + 7)(x - 8) - Multiply 4x and x

(4x + 7)(x - 8) - Multiply 4x and -8

     -32x

(4x + 7)(x - 8) - Multiply 7 and x

     7x

(4x + 7)(x - 8) - Multiply 7 and -8

     -56

Now, add all of the terms together.

-32x+7x-56

    -32x+7x = -25x

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
