Find the dimension of a rectangle whose width is 10 miles less than its length and whose area is 75 square miles

The length is 15 miles and the width is 5 miles.

Step-by-step explanation:

The rectangle has two dimensions, width w and length l.

The area is given by the following formula:

.

In this problem, we have that:

The width is 10 miles less than its length. This means that

The area is 75 square miles. So

.

and .

We cannot have negative dimensions. This means that the length is 15 miles and the width is 5 miles.

.

step-by-step explanation:

.

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.
