N the example, explain how the term 9··4x was obtained in the expression for the perimeter 2 To find the value of x in the equation 9··4x 1 2 5 20, you first get the term with x by itself on one side of the equation How can you do that? What equation do you then have?3 How can you find the value of x in the equation you wrote for problem 2? What is the value of x?4 Find the length of each side of the triangle Check that the perimeter is equal to 20 inches Show your work. Solution: Example The perimeter of the triangle shown is 20 inches Write an expression for the perimeter Then write an equation that you can use to find the length of each side Perimeter: (x 2 4) 1 (x 1 1) 1 1 1··4x 1 5 2 = 9··4x + 2 Equation: 9··4x + 2 5 20 x 2 4x 1 1 x 1 5

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
