The length, width, and height of a rectangular prism can be represented by the expressions (x+3), (x+7) and (x-1). what is the volume of the prism?

Ans:

x^3 + 9x^2 + 11x - 21

Step-by-step explanation:

length * width * height = volume

(x+3)(x+7)(x-1)

(x+3)(x+7)(x) + (x+3)(x+7)(-1)

x^3 + 10x^2 + 21x - x^2 - 10x - 21

x^3 + 9x^2 + 11x - 21

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
