Answer:
El mayor lado del rectángulo es de 10 cm
Explicación paso a paso:
Perímetro de un rectángulo: es el doble de la suma de sus lados
P = 2 (a+b)
a: es el ancho del rectángulo
b: es el largo del rectángulo
Uno de los lados es 6cm mas que el otro lado
b= a + 6 cm
Sustituimos en la ecuación de perímetro:
28cm /2 = a+a+6cm
14cm = 2a +6 cm
14cm-6cm = 2a
a = 4 cm
b = 10cm
El mayor lado del rectángulo es de 10 cm

Answer:
The rock remains in the air for t = 3.832 s
Step-by-step explanation:
To easily solve this equation, we can graph the equation with a calculator and see the interval for which the rock remains in the air.
(There is a minor problem with the equation, the last term should be 120 to model the 120 ft building)
h(t)= -16t^2 -30t + 120
Please see attached picture for the graph.
The time it takes for the ball to hit ground can be found by making
h(t) = -16t^2 -30t + 120 = 0
In the graph this point is equal to
t = 3.832 s
h(t) = 0
