What is he product of (n-8)(n+2)

liubo4ka [24]

Answer:

$\large\boxed{(n-8)(n+2)=n^2-6n-16}$

Step-by-step explanation:

Use FOIL:

<em>(a + b)(c + d) = ac + ad + bc + bd</em>

We have:

$(n-8)(n+2)=(n)(n)+(n)(2)+(-8)(n)+(-8)(2)=n^2+2n-8n-16$

<em>combine like terms</em>

$=n^2+(2n-8n)-16=n^2-6n-16$

goldenfox [79]

<h3>Zara earned $ 134 on friday including commission</h3>

<em><u>Solution:</u></em>

Given that,

zahra earns $80 each day plus a 6% commission on her sale at an appliance store

zahra has $900 in sales

<em><u>Find the commission amount</u></em>

commission amount = 6 % of 900

$commission\ amount = \frac{6}{100} \times 900\\\\commission\ amount = 54$

Zara earnings including commission amount = 80 + 54 = 134

Thus Zara earned $ 134 on friday including commission
