Answer: X= 21

Step-by-step explanation: Let's solve your equation.

x/3 = 7

Step 1: Multiply both sides by 3.

X/3 * (3) = 7 * (3)

The 3 multiplied with X over three will end up being just X. Then you times 7 by 3 and end up getting 21.

X= 21

Simple...

y=x^{2} -9

y= x^{2} -9

It's quite easy to see x^{2} = x^{2}

Thus, any value of x makes the equation true.

Thus, your answer.

un rectangulo tiene 28 cm de perimetro y unos de sus lados mide 4 cm ¿cuantos cuadrados de 2 cm por lado se mecesitan para armar
seraphim [82]

Answer:

10 cuadrados

Step-by-step explanation:

Si uno de los lados de rectangulo es de 4cm entonces el lado parallelo tambien es de 4cm. Eso nos da 8cm del perimetro y nos quedan los otros dos lados que tienen la misma medida. Entonces dividimos el resto del perimetro por 2.

28 - 8 = 20cm

20cm / 2cm = 10cm

Ahora que tenemos todas las medidas podemos multiplicar el largo por el ancho para calcular el area del rectangulo

10cm * 4cm = 40cm^{2}

el cuadrado de 2cm tendra un area de

2cm * 2cm = 4cm^{2}

Ahora simplemente dividimos el area del rectangulo por el area del cuadrado para saber cuantos cuadrados necesitamos para armar ese rectangulo

40cm^{2} / 4cm^{2} = 10 cuadrados
