5. (9r 3 + 5r 2 + 11r) + (-2r 3 + 9r - 8r 2)

ad-work [718]

Answer:

7r³ - 3r² + 20r

Step-by-step explanation:

(9r³ + 5r² + 11r) + (-2r³ + 9r - 8r²)

You can get rid of the parentheses since there is nothing to distribute.

9r³ + 5r² + 11r - 2r³ + 9r - 8r²

Combine like factors.

7r³ - 3r² + 20r

Hey There!!

The answer is below!!

Step-by-step explanation:

We move all terms to the left:

$-6n+22-(-4n+14-10n+22)=0$

We add all the numbers together, and all the variables

$-6n-(-14n+36)+22=0$

We get rid of parentheses

$-6n+14n-36+22=0$

After that, We add all the numbers together, and all the variables

$8n-14=0$

Then, We move all terms containing n to the left, all other terms to the right

$8n=14$

$n=14/8$

$n=1+3/4$

I don't know this is $100$ % right....

$So.....GoodLuck!!$

# $Be$ $Bold$

# $Always$ $Brainly!$
