Kelly was given square piece of material whose dimensions were 5x inches by 5x inches. she felt that it was a little too big for the project she was working on, so she cut 2 inches off each side of the square. which of the following expression represents the area of the remaining piece of material, in square inches?

25x^2 - 20x + 4

Explanation:

Multiply (5x-2) by (5x-2).

25x^2 - 10x - 10x + 4.

Hope this helps!

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

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
