Answer:

<h3> $\boxed{ \bold{ 6x + 11}}$ </h3>

Step-by-step explanation:

$\mathsf{3(4x + 1) - 2(3x - 4)}$

Distribute 3 through the parentheses

$\mathsf{12x + 3 -2(3x - 4)}$

Distribute 2 through the parentheses

⇒ $\mathsf{12x + 3 - 6x + 8}$

Collect like terms

⇒ $\mathsf{6x + 11}$

Hope I helped!

Best regards!!

Answer:

Step-by-step explanation:

Once

$\sqrt{xy} = 6$

We know that $xy = 36$

There are infinity values for $x, y$ , but considering $x, y \in \mathbb{Z}$

Below we have all the solutions for $x, y$

Negative:

$\\x = -36 \text{ and } y = -1\\x = -18 \text{ and } y = -2\\x = -12 \text{ and } y = -3\\x = -9 \text{ and } y = -4\\x = -6 \text{ and } y = -6\\x = -4 \text{ and } y = -9\\x = -3 \text{ and } y = -12\\x = -2 \text{ and } y = -18\\x = -1 \text{ and } y = -36\\$

Positives:

$x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and } y = 3\\x = 9 \text{ and } y = 4\\x = 6 \text{ and } y = 6\\x = 4 \text{ and } y = 9\\x = 3 \text{ and } y = 12\\x = 2 \text{ and } y = 18\\x = 1 \text{ and } y = 36\\$

We can see that $x + y \neq 18$

#5-12 you don't need to answer just plz explain how to do it

laiz [17]

Find common variables. I wrote the ones I found above the polynomial. write them in parentheses the first number will have the variable. now it's just a matter of figuring out how to order it so that the first terms added to the second terms equal to the middle term of the polynomial. ... I think this is right. you could always look on wikiHow if I'm wrong.
