El polinomio que representa el volumen da la caja es Base:20x+3 Ancho:x+y alto:5y-1
POrfa nesecito ayuda.....
V=(20x+3)(x+y)(5y-1)
V=(20x+3)(5xy-x+5y²-y)V=100x²y-20x²+100xy²-20xy+15xy-3x+15y²-3y
V=100x²y-20x²+100xy²-5xy-3x+15y²-3y
*Recuerda que:
Volumen=(base)*(ancho)*(alto)
-Reemplazamos:
V =(20x+3)(x+y)(5y-1)
V =(20x+3)(5xy-x+5y²-y)V =100x²y-20x²+100xy²-20xy+15xy-3x+15y²-3y
V =100x²y-20x²+100xy²-5xy-3x+15y²-3y
*Ten cuidado con los signos.
-Espero haberte ayudado, saludos.
