Multiply the First<span> terms
</span>Multiply the Outside<span> terms
</span>Multiply the Inside<span> term
</span>Multiply the Last<span> terms
</span>Simplify

Understand factoring.

Write a space for the answer in FOIL form.<span>
Don't write + or - between the blank terms yet, since we don't know which it will be.
</span>
<span>Fill out the First terms.
</span>
<span>Use factoring to guess at the Last terms.
</span>
<span>Test which possibilities work with Outside and Inside multiplication.
</span>
<span>Use simple factoring to make more complicated problems easier.
</span>
<span>Look for trickier factors.
</span>
<span>Solve problems with a number in front of the x^2.
</span>
<span>Use substitution for higher-degree trinomials.
</span>
Check for prime numbers.

Check to see if the trinomial is a perfect square.

<span>Check whether no solution exists.
</span>
If both binomials have the same variables to the same powers, then it is true. In general, multiplying binomials gives four terms, one corresponding to each letter of the FOIL acronym. So, you only get a trinomial when the O and I terms combine.

Calculate the mass of sodium azide (2NaN3) required to decompose and produce 1.20 moles of nitrogen.
Ad libitum [116K]

Answer:

The answer to your question is:  40.8 g of NaN₃

Step-by-step explanation:

NaN₃ mass = ?

nitrogen = 1.2 moles

Equation

                           2NaN₃      ⇒ 2Na  +  3N2

                          2 moles of NaN₃  -----------------   3 moles of N₂

                           x                          ------------------   1.2 moles of N₂

                          x = (1.2 x 2) / 3

                          x = 2.4/ 3

                         x = 0.8 moles of NaN₃

MW NaN₃ = 23 + 28

                = 51 g

                         51 g of NaN₃ ----------------- 1 mol

                         x                    ----------------- 0.8 mol

                         x = (0.8 x 51) / 1

                        x = 40.8 g of NaN₃

Emmanuel brought 28 lb of potting soil this week. This amount is 4 lb more than twice the amount of potting soil he brought last
jek_recluse [69]
(a) how much potting soil he bought last week
(b) 28 = 2p + 4
(c) 28 = 2p + 4....subtract 4 from both sides
     28 - 4 = 2p...simplify
     24 = 2p...divide both sides by 2
     24/2 = p....simplify
     12 = p......12 solves the equation
(d) He bought 12 lbs of potting soil last week

Which of the following companies offers the greatest total employment compensation? Company A Gross pay $38,200 Insurance $3,500
spayn [35]

Answer:

Company C offers the greatest total employment compensation.

Step-by-step explanation:

Now we calculate the greatest total employment compensation as follows:

Company A :

Gross pay -      $38,200

Insurance -       $3,500

Paid time off -  $4,100

Total compensation = 38,200 + 3,500 + 4,100 = $45,800

Company B :

Gross pay -                         $39,000

Total employee benefit -   20% of 39,000 (0.20 × 3900) = $7,800

Job expenses -                  $700

Total compensation =  39,000 + 7,800 + 700 = $47,500

Company C :

Gross pay -     $39,900

Insurance -      $3,200

paid time off -  $3,900

Job expenses- $1,000

Total compensation = 39,900 + 3,200 + 3,900 + 1,000 = $48,000

Company D:

Gross pay - $39,400

total employee benefits - 18% of 39,400 (0.18 × 39,400) = $7,092

Total compensation = 39,400 + 7,092 = $46,492

Therefore company c offers the greatest total employment compensation.
