Answer:

<h2>This is not a direct variation.</h2>

Step-by-step explanation:

Direct variation:

<em>mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.</em>

<em>(y varies directly with x with a constant variation of k)</em>

$y=kx;\ k\neq0$

$y=kx\qquad|\text{divide both sides by}\ x\\\\\dfrac{y}{x}=k\Rightarrow \dfrac{y}{x}=constant$

$21.\\\\x=y+2\qquad|\text{subtract 2 from both sides}\\\\x-2=y\qquad|\text{divide both sides by}\ x\\\\1-\dfrac{2}{x}=\dfrac{y}{x}\ro\dfrac{y}{x}=1-\dfrac{2}{x}\neq constant$

The pool has area $160\,\mathrm{ft}^2$ .

Let $x$ be the width of the sidewalk. Then the combined area of the pool and sidewalk is $(10+x)(16+x)=160+26x+x^2$ , so that the area of the sidewalk alone is $26x+x^2$ .
