Simplify<br> (7x - 7)(x + 1)
Nadusha1986 [10]

We will use the FOIL method to solve this.

(7x-7)(x+1)

Multiply 7x by x. Then, multiply 7x by 1. Then, multiply -7 by x. Then, Multiply -7 by 1.

7x^{2} + 7x - 7x -7

Now, we need to simplify by combining like terms.

7x^{2} -7

If you look, -7x and 7x are gone. This is because they cancel each other out.

I hope this helped and maybe consider giving me brainliest :)

Assume Pina Colada Corp. uses the periodic inventory system and has a beginning inventory balance of $5800, purchases of $65000,
babymother [125]

The inventory account expected to have by December 31 is more than $5800. Option C

<h3>How to calculate the end inventory</h3>

The formula for end inventory is given as ;

Ending inventory = Beginning inventory + net purchases –sales

Beginning inventory = $5800

Net purchases = $65000

Sales = $112000

Put into the formula

Ending inventory = $ 5800 + 65000 - 112000

Add first,

Ending inventory = $ 70800 - 112000

Ending inventory = $ -41, 200

Thus, the inventory account expected to have by December 31 is more than $5800. Option C
