Question

El perímetro del rectángulo es...

Answer 1

Respuesta:

$4x^3+2y-2xy-\frac{1}{2}$

Explicación paso a paso:

$\left(2x^3+y\right)+\left(2x^3+y\right)+\left(-\frac{1}{4}-xy\right)+\left(-\frac{1}{4}-xy\right)$

$2x^3+y+2x^3+y-\frac{1}{4}-xy-\frac{1}{4}-xy$

$4x^3+2y-2xy-\frac{1}{4}-\frac{1}{4}$

$4x^3+2y-2xy+\frac{-2}{4}$

$4x^3+2y-2xy-\frac{1}{2}$
