When a function intersects with the x-axis, it's y value must be 0. That means when the straight line intersects with the axis, it's at the point (4k,0), so plugging those numbers into our original equation yields:
The area of the deck is 36 square feet.
<u>Solution:</u>
Assume l is the length of the deck; w is its width, P is its perimeter and A is its area.
Given that length of a rectangular deck is 4 times its width
Perimeter of the deck is 30 ft
On substituting all the given values in (2) we get,
On dividing we get,
If w=3,
On substituting the values in the above formula we get,
