Which expression is equal to 6rs^9/42r^5s^2

1 answer:

6 0

$\dfrac{6rs^9}{42r^5s^2}=\dfrac{6}{42}\cdot\dfrac{r}{r^5}\cdot\dfrac{s^9}{s^2}=\dfrac{1}{7}\cdot\dfrac{1}{r^4}\cdot\dfrac{s^7}{1}=\boxed{\dfrac{s^7}{7r^4}}$

Which of the following theorems proves that abc~def?

GaryK [48]

Answer:

D but read below.

Step-by-step explanation:

I take it that the symbol ~ stands for similar. If that is so, then the answer you want is AA, because if 2 angles in a triangle are equal, then all 3 are. So if any 2 equal angles in one triangle are equal to 2 angles in another, then the two triangles are similar.

Which equation demonstrates the multiplicative identity property?

Anna007 [38]

The equation $\boxed{a + b = a = b + a}$ demonstrates the multiplicative identity.

Further explanation:

The equation that satisfies the condition of multiplicative identity for the complex number can be represented as,

$a \times b = a = b \times a$

Here, $a$ is the multiplicative identity and it can be observed that the multiplicative identity would be 1 where $b$ is the complex number.

The equation that satisfies the condition of additive identity for the complex number can be represented as,

$a + b = a = b + a$

Here, $a$ is the additive identity and it can be observed that the additive identity would be 0 where $b$ is the complex number.

Consider an example $\left( { - 3 + 5i} \right) + 0 = - 3 + 5i$ .

It can be observed that the equation $\left( { - 3 + 5i} \right) + 0 = - 3 + 5i$ satisfies the condition of the additive identity as 0 is the additive identity.

Consider an example $\left( { - 3 + 5i} \right)\left( 1 \right) = - 3 + 5i$ .

It can be observed that the equation $\left( { - 3 + 5i} \right)\left( 1 \right) = - 3 + 5i$ satisfies the condition of the multiplicative identity as 1 is the multiplicative identity.

Here, $a{\text{ is }}\left( { - 3 + 5i} \right)$ by comparing the general equation $a \times b = a = b \times a$

Therefore, the second example $\left( { - 3 + 5i} \right)\left( 1 \right) = - 3 + 5i$ demonstrates the multiplicative identity.

Thus, in general the equation $a + b = a = b + a$ demonstrates the multiplicative identity.
