4.) What is the area of a rectangle with length 4x2y inches and width (5x3 + 2x2 + 7) inches? Write your answer as an expression in terms of x and y.
5.) The length of a rectangle is 3 inches greater than the width.
a. Write a polynomial that represents the area of the rectangle.
b. Find the area of the rectangle when the width is 4 inches.

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
