Note that c is the hypotenuse of the blue triangle, and that the Pyth. Thm. states that (length of one leg)^2 + (length of the other leg)^2 = (hyp)^2.

Therefore, (hyp)^2 = c^2 = [2sqrt(x^2+3x)]^2 + 3^2, or
                                        = 4(x^2+3x) + 9, or
                                        = 4x^2 + 12x + 9  = (2x+3)^2
Taking the sqrt of both sides, c = plus or minus (2x+3).  Eliminate -(2x+3) because the middle term of the square of this would be negative, in conflict with the given +12x.

c=2x+3 is the correct answer.

Mr. Greenwood bought 1/2 gallon of milk . His family members drank 3/4 of the milk for breakfast. How many gallons of milk did t
Marina CMI [18]

Given:

Mr. Greenwood bought 1/2 gallon of milk.

His family members drank 3/4 of the milk for breakfast.

To find:

How many gallons of milk did they drink ?

Solution:

We have,

Total milk = \dfrac{1}{2} gallon

Milk drink by them = \dfrac{3}{4} of the milk

                               = \dfrac{3}{4}\times \dfrac{1}{2} gallon

                               = \dfrac{3}{8} gallon

Therefore, they drink \dfrac{3}{8} gallon of milk.

Los profesores de un colegio tienen planeado mandar 6 boletines informativos al año a cada una de las 620 familias con estudiant
alekssr [168]

Answer:

14.88 resmas

Step-by-step explanation:

Los maestros de una escuela planean enviar 6 boletines al año a cada una de las 620 familias con estudiantes en la escuela.

Esto significa: El número total de boletines que recibe cada familia = 6 × 620 familias

= La escuela envía 3720 boletines cada año

Cada uno de los boletines necesita 2 hojas de papel.

1 boletín = 2 hojas de papel

3720 boletines =

Cruz multiplicar

3720 boletines × 2 hojas

= Se necesitan 7440 hojas de papel en un año

El papel se vende en resmas de 500 hojas.

¿Cuál es la cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año?

500 hojas de papel = 1 resma

7440 hojas de papel = y

Cruz multiplicar

500 × y = 7440 × 1

y = 7440/500

y = 14.88 resmas

La cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año es 1488 resmas
