Answer:
k=45
Step-by-step explanation:
k

+3=18
Step 1: Simplify both sides of the equation.

3
k+3=18
Step 2: Subtract 3 from both sides.

k=15
Step 3: Multiply both sides by 3.

Answer:
A person saves 30.7 yards
Step-by-step explanation:
the path a person walks diagonally creates a right triangle with the lenght and the width of the rectangular piece of land. The diagonal is 90 yards which becomes the hypotenuse.
let <em><u>w</u></em> be the width, then <em><u>l</u></em> becomes the length, which is twice the width. Therefore, leg <em><u>l=2</u></em><u>a</u> and leg <u><em>w=</em></u><u>a</u>.
By the Pythagorean Theorem:
Replacing the values:
But that <u>a</u> is the value for the width, if a person walks the width and the length, it becomes:
the length plus the width=2a+a=3a.
So:
Now, the difference between walking across the land and surrounding it, is:
We can conclude, a person saves 30.7 yards if walking across the land.
