The width of a rectangle is 4x - 4.5 feet and the length is 4.5x+7 feet. Find the perimeter of the rectangle.

17x+5

Step-by-step explanation:

1. Perimeter of triangle

P = 2(L +W)

P = 2((4.5x+7) + (4x-4.5)) = 2(8.5x+2.5)

P = 17x+5

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

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
