Sam decides to build a square garden. if the area of the garden is 25x2 + 30x + 9 square feet, what is the length of one side of the garden?
a) (3x + 5) feet
b) (3x − 5) feet
c) (5x + 3) feet
d) (5x − 3) feet

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

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
