$\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
\\\\
&&y=\cfrac{{{ k}}}{x}&\impliedby 
\begin{array}{llll}
k=\textit{constant}\\
\qquad \textit{of variation}
\end{array}
\end{array}\\\\

$

$\bf y=\cfrac{k}{x}\qquad 
\begin{cases}
y=0.2\\
x=0.3
\end{cases}\implies 0.2=\cfrac{k}{0.3}\implies 0.2\cdot 0.3=k
\\\\\\
\textit{thus, the equation will be}\quad y=\cfrac{0.06}{x}$

The length of a rectangle is five less than its width. The area of the rectangle is 84 square feet. Write a quadratic equation i

salantis [7]

Given:

The length of a rectangle is 5 less than its width.

The area of the rectangle is 84 square feet.

We need to determine the quadratic equation in standard form that represents the area of the rectangle.

Dimensions of the rectangle:

Let l denote the length of the rectangle.

Let w denote the width of the rectangle.

Since, it is given that the length is 5 less than its width, it can be written as,
