The length of a rectangle is 2 units shorter than one-fifth of the width, x. which expression represents the perimeter of the rectangle?

perimeter = 2L+2w

from the problem L = 1/5w-2

so perimeter = 2(1/5w-2) +2w

= 2/5w-4 +2w

=12/5w-4

without seeing your choices it should be similar to this

Perimeter =

Step-by-step explanation:

Let the length of a rectangle is l and width is w.

Then the expression which represents the perimeter is

P = 2(l + w)

It is given in the question length of the rectangle = l and width = x

and l =

By replacing these values in the expression for the perimeter

P =

  =

  =

Therefore, expression that represents the perimeter of the rectangle will be

Perimeter =

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
