Convertimos el volumen a litros. Recordamos que 1 metro cúbico de agua equivale a 1 000 litros. Podemos utilizar una regla de tres simple, revisamos los datos y luego realizamos nuestras operaciones……………………………………………………………… …… Si cada 5 días la familia compra agua al camión cisterna, respondemos: ¿cuánto gastarán (en soles) la familia aproximadamente en un mes?
¿El volumen de agua consumido se aproxima a los señalado por SEDAPAL o SUNASS?, ¿de qué manera esta situación puede afectar la salud de la familia?

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
