The length of a rectangle is eight more than twice its width. The perimeter is 88 feet. Find the dimensions of the rectangle. A w = 10 ft, l = 18 ft

B w = 16 ft, l = 28 ft

C w = 18ft, l = 24 ft

D w = 12 ft, l = 32 ft

D w = 12ft, l = 32ft

Explanation:

Make an equation for your length based on the given information.

l = 2w + 8

Make an equation using what you know about the perimeter

p =2l + 2w, p = 88

88 = 2l +2w

Substitute in your previous equation for l.

88 = 2(2w + 8) + 2w

Distribute and simplify.

88 = 4w + 16 + 2w

88 = 6w + 16

72 = 6w

w = 12

Now you can solve for l using the first equation.

l = 2(12) + 8

l = 32

Your answer is w = 12fr, l = 32ft. You can check your work by plugging the values back into the perimeter equation.

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

d.) yes, because the volume of the cone is greater than the volume of the sphere
