It would help to find the surface area now, double the dimensions, find the new surface area, and compare.

The surface area of a cylinder is:

2 * pi * r^2 + 2 * pi * r * h

So, the surface area is:

2 * pi * 64 + 2 * pi * 4 = 136 pi

Double the dimensions:

2 * pi * 256 + 2 * pi * 16 = 544 pi

544 pi divided by 136 pi = 4

So, the answer is 4.

Averi estaba intentando factorizar 4x^2+20x-164x
Darina [25.2K]

Responder:

El ancho del modelo de área de Averi será x² + 5x-4

Explicación paso a paso:

Deje que el área del modelo de Averi sea igual a la ecuación dada

4x² + 20x-16

Si el mayor factor común del modelo es 4, esto significa que 4 se puede factorizar fácilmente de la ecuación como se muestra;

4 * (x² + 5x-4) ... (1)

Si la fórmula para el modelo de área = Largo * Ancho

Al comparar la fórmula para encontrar el área del modelo con la ecuación 1, el ancho del modelo de área será la función entre paréntesis, es decir,

x² + 5x-4

El ancho del modelo de área de Averi será x² + 5x-4
