Answer 1

Answer:

The width is: $w(x)=4x^2$

The length is $l(x)=2x^2+3x+5$

Step-by-step explanation:

The given rectangle has area given algebraically by the function:

$a(x)=8x^5+12x^3+20x^2$

The width of the rectangle is the greatest common factor of $8x^5$,  $12x^3$ and $20x^2$

That is the width is: $w(x)=4x^2$

We now divide the area by the width to obtain the length of the rectangle:

$l(x)=\frac{8x^5+12x^3+20x^2}{4x^2}$

This simplifies to:

$l(x)=\frac{8x^5}{4x^2}+\frac{12x^3}{4x^2}+\frac{20x^2}{4x^2}$

$l(x)=2x^2+3x+5$

Answer 2

Answer:

The width is:  $4x^{2}$

The length is:  $2x^{3} +3x+5$
