The perimeter of a rectangle is 66 inches. if the length is 3 less than five times the width, find the length and width.

Step-by-step explanation:

Let w represent the width of the rectangle. The perimeter is twice the sum of length and width so is ...

  P = 2(L + w) . . . . . . equation for perimeter

  66 = 2((5w-3) +w) . . . substitute the given values

  33 = 6w -3 . . . . . . . divide by 2 and collect terms

  36 = 6w . . . . . . . . . add 3

  6 = w . . . . . . . . . . . .divide by 6

  L = 33-6 = 27

The length is 27 inches; the width is 6 inches.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
