Answer with Step-by-step explanation:

The Reflexive property states that for every real number x, x=x

Division property states that if a=b and we divide it by any non zero number c then also a/c=b/c

Multiplication property states that if a=b and we multiply it by any number c then also ac=bc

Addition property states that if a=b and we add it by any number c then also a+c=b+c

We are given that x= -6

Adding both sides by 6

⇒ x+6=0

Hence, it justifies the addition property.

Hence, correct option is:

D, Addition

Julia examines the two triangles below and determines that .

baherus [9]

IN Δ MLN:

∠M = 18.3 , ∠L = 98.6 AND ∠N = 180 - (∠M + ∠L) = 180 - (18.3 + 98.6 ) = 63.1

IN Δ FGH:

∠F = 98.6 , ∠G = 61.1 AND ∠H = 180 - (∠F + ∠G ) = 180 - (98.6 + 61.1 ) = 20.3

∴ ONLY ∠N = ∠F = 98.6

There is no other congruent angles

So, The correct statement is :

Inaccurate. The triangles are not similar because angle M is not congruent to angle H, and angle N is not congruent to angle G.

A hot tub has capacity of 1458 liters 487 liters and 750 ml were put in how much more needs to be put in

Colt1911 [192]

Well the easiest way we can do it is convert liters in to milliliters and since there are 1000 milliliters in a liter multiply 1458 by 1000 and 487 by 1000 which will get you 1458000 milliliters of capacity and the 487 liters turns into 487000 mililiters we add this to the 750 milliliters to get 487750 milliliters. Now it is all a matter of subtracting to find out how much more needs to be put in. 1458000-487750=970250 milliliters. So the amount needed to fill the hot tub is 970250 ml or if you want to convert it back to liters 970.250 l

I’m doing edg unit test what is the answer to. Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?

sertanlavr [38]

Answer:

(4x + 1)(x² - 2)

Step-by-step explanation:

Given

4x³ + x² - 8x - 2 ( factor the first/second and third/fourth terms )

= x²(4x + 1) - 2(4x + 1) ← factor out (4x + 1) from each term

= (4x + 1)(x² - 2)

Need your Help please!!

lianna [129]

Answer:

f(x) = (x + 2)(x + 1)(x - 3) = x^3 - 7·x - 6

a = 0 ; b = -7 ; c = -6

a = -3 ∧ b = -2 ∧ c = -3

La densidad de un líquido es de 1.5 gr/cm3 su masa es de 7 libras Determina la cantidad de litros que ocupan dichos líquidos

egoroff_w [7]

Answer:

La cantidad de litros que ocupa dicho líquido es:

2,12 Litros

Step-by-step explanation:

El volumen de un líquido puede obtenerse al tener tanto su densidad como su masa usando la siguiente fórmula:

Densidad = masa / volumen

Al despejar volumen se obtiene:

Volumen = masa / densidad

Por lo cual, si se reemplazara la fórmula quedaría:

Volumen = 7 Lb / 1.5 gr/cm^3

Sin embargo, para operar, las unidades en las que se expresa la masa deben coincidir con las unidades de la densidad, por lo cual vamos a convertir las libras en gramos teniendo en cuenta el siguiente factor de conversión:

1 libra = 453,592 gramos

Entonces:

7 lb = 453,592 gr * 7 = 3175,144 gr

Ahora este valor reemplaza la masa en la fórmula y calculamos:

Volumen del líquido = 3175,144 gr / 1.5 gr/cm^3

Volumen del líquido = 2116,762667 cm^3 (He utilizado todos los decimales para obtener el resultado exacto).

A simple vista ya se tiene el volumen del líquido en cuestión, sin embargo, el ejercicio pide que sea expresado en litros, por lo cual vamos a convertir los centímetros cúbicos en litros teniendo en cuenta el siguiente factor de conversión:

1 litro = 1000 centímetros cúbicos.

Ahora podemos aplicar una regla de tres simple, si:

1000 cm^3 = 1 L
2116,762667 cm^3 = x

Y operamos:

x = (2116,762667 cm^3 * 1 L) / 1000 cm^3
x = 2,116762667 L

O si quieres un valor aproximado:

x = 2,12 Litros.

Entonces, la cantidad de litros teniendo en cuenta la densidad y la masa brindadas es 2,12 litros.
