Let's factor the top and the bottom.
Top factors 4x + 20 = 4(x + 5)
Bottom x^2 + 2x - 15 = (x + 5)(x - 3)
The gcf is the largest value that will go into both the top and the bottom. In our problem the ONLY thing that will go into top and bottom is x + 5 so that is your GCF. (c)
Responder:
3 / 4x + 1/2 = x
Explicación paso a paso:
Dado que:
Capacidad total = x
Volumen inicial = cierta fracción * capacidad total
Volumen adicional agregado para llenar = 1/2
Por eso,
Inicial. Volumen + volumen adicional = volumen total
De las opciones:
Un volumen inicial de 3 / 4x
Volumen adicional de 1/2
Volumen total = x
Sumar todo hace que la ecuación:
3 / 4x + 1/2 = x
x - 3 / 4x = 1/2
Por lo tanto, la ecuación correcta de la opción es: 3 / 4x + 1/2 = x
