Answer:

Step-by-step explanation:

the straight sides are just 4.5 *2 = 9 cm

the arcs are  2\pir * Ф/360

where Ф= 50 for this problem

and r = 8

the inner arc is  2\pi(3.5) *50/360 = 3.05432

the outer arc is 2\pi(8)*50/360 = 6.98131

total is 19.0356

to 3 sig figs is 19.036  :)

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
