Answer: the length is 6 feet. The width is 2 feet
Step-by-step explanation:
The garden pool is rectangular in shape.
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The area of a rectangle is expressed as L× W. The area of the rectangular garden pond is 12ft^2. It means that
L× W = 12 - - - - - - - - - - 1
The length of the pool needs to be 2ft more than twice that width. This means that
L = 2W + 2 - - - - - - - - - - - 2
Substituting equation 2 into equation 1, it becomes
W(2W + 2) = 12
2W^2 + 2W = 12
2W^2 + 2W - 12 = 0
W^2 + W - 6 = 0
W^2 + 3W - 2W - 6 = 0
W(W + 3) - 2(W + 3) = 0
W - 2 = 0 or W + 3 = 0
W = 2 or W = - 3
Since the Width cannot be negative, then the width is 2 feet
Substituting W = 2 into equation 2. It becomes
L = 2×2 + 2 = 6 feet
Answer:

Step-by-step explanation:
Answer:???
Step-by-step explanation:
Usando proporciones, en conjunto con multiplicación cruzada, encontra-se que el valor de p es de 6.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total, e puede ser encontrada aplicando una regla de três.
En este problema, relación es dada por:
Aplicando multiplicación cruzada:
8p = 6(p + 2)
8p = 6p + 12
2p = 12
p = 12/2
p = 6.
