Una piscina rectangular de 15 m de largo por 9m de ancho está rodeada por un camino de cemento de ancho uniforme. ¿Si el área de
malfutka [58]

Answer:

El ancho del camino es 1.5 m.

Step-by-step explanation:

Una piscina rectangular posee 15 m de largo por 9 m de ancho.

El área de un rectángulo es igual a la base por la altura. Es decir, lado mayor por lado menor. Entonces el área de la piscina es 15 m* 9 m= 135 m²

La piscina está rodeada por un camino de cemento de ancho uniforme, al cual se denomina x y estará en unidades de metros (m). Entonces el largo de la piscina sumado al ancho a ambos lados de la piscina será 15 m + 2*x, mientras que el ancho de la piscina sumado al largo a ambos lados de la piscina es 9 m + 2*x. Entonces este área se puede expresar como

(15 m+2*x)*(9 m+ 2*x)

Entonces al área de la piscina sumado al camino se le resta el área de la piscina y da como resultado el área del camino, cuyo valor es 81 m²:

El área total - área de la piscina =  área del camino

(15 m +2*x)*(9 m+ 2*x) - 135 m²= 81 m²

Resolviendo:

15*9 m²+15*2*x + 9*2*x + 2*x*2*x - 135 m²= 81 m²

135 m² + 30*x + 18*x + 4*x² - 135 m²= 81 m²

48*x + 4*x² = 81 m²

48*x + 4*x² - 81 m²= 0

Siendo una ecuación cuadrática donde a= 4, b= 48 y c= -81, entonces:

\frac{-48+-\sqrt{48^{2}-4*4*(-81) } }{2*4}

Resolviendo:

\frac{-48+\sqrt{48^{2}-4*4*(-81) } }{2*4}= 1.5

\frac{-48-\sqrt{48^{2}-4*4*(-81) } }{2*4}= -13.5

Como las distancias solo pueden ser positivas, entonces <u><em>el ancho del camino es 1.5 m.</em></u>

What is the graph of the function f(x) = the quantity of x squared plus 4 x minus 12, all over x plus 6 ? (1 point)
krek1111 [17]
X^2 + 4x -12 = (x+6)(x-2)

so
(x+6)(x-2)
---------------- = x - 2
x + 6

f(x) = x -2


because
if x = -6
then y = -6 - 2 = -8

(-6,-8) is the order pair
