Al sumar y/o restar números decimales, siempre se debe aplicar la norma de los signos. * 1 punto FALSO VERDADERO

Luden [163]

Answer:

La norma de los signos es para el producto de números reales, y la norma es la siguiente.

(+)*(+) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(-)*(-) = (+)

Es decir, el producto de dos números de mismo signo es siempre positivo

El producto de dos números de distinto signo es siempre negativo.

Particularmente, para la suma esta norma no funciona (pues no está definida para la suma)

Pero en casos como:

5 - (-4)

(esto sería: "la diferencia entre cinco y menos cuatro")

notar que podemos reescribir esto como:

5 + (-1)*(-4)

Ahora podemos aplicar la norma de los signos:

5 + 4 = 9

Donde aplicamos la norma de los signos,

Podemos concluir que, si bien es una regla que aplica al producto, siempre la tenemos que tener en cuenta en cualquier operación que hagamos.

Por lo podemos concluir que la respuesta correcta es verdadero.

The length of a rectangle is 8cm greater than twice its width. Find the dimensions if the area

aleksandr82 [10.1K]

Answer:

Length $14\ cm$

Width $3\ cm$

Step-by-step explanation:

Let

x-----> the length of rectangle

y ----> the width of rectangle

we know that

The area of rectangle is equal to

$A=xy$

$A=42\ cm^{2}$

so

$42=xy$ ----> equation A

$x=2y+8$ ---> equation B

substitute equation B in equation A and solve for y

$42=(2y+8)y\\ \\2y^{2}+8y-42=0$

Solve the quadratic equation by graphing

The solution is $y=3\ cm$

see the attached figure

Find the value of x

$x=2(3)+8=14\ cm$

therefore

Length $14\ cm$

Width $3\ cm$
