Divide (-3x^2 - 9x) ÷ (x + 3) <br> please explain/show work! &lt;33
Stolb23 [73]

Step-by-step explanation:

<em>( - 3 {x}^{2} - 9x) \div (x + 3)</em>

<em>This </em><em>is </em><em>the</em><em> </em><em>original </em><em>equation</em><em> </em><em>so</em><em> </em><em>you </em><em>will</em><em> </em><em>open</em><em> </em><em>the</em><em> </em><em>brackets</em><em>.</em>

<em>- 3 {x}^{2}  - 9x \div x + 3</em>

<em>The</em><em> </em><em>x</em><em> </em><em>will</em><em> </em><em>cross</em><em> </em><em>the</em><em> </em><em>division </em><em>sign</em><em> </em><em>making</em><em> </em><em>it</em><em> </em><em>times</em><em> </em><em>x</em><em>.</em>

<em>3 {x}^{2}  - 9x \times x = 3</em>

<em>So</em><em> </em><em>you </em><em>will</em><em> </em><em>proceed</em><em> </em><em>to</em><em> </em><em>multiply</em><em> </em><em>the</em><em> </em><em>9</em><em>x</em><em> </em><em>by</em><em> </em><em>x</em><em> </em><em>making </em><em>it</em><em>;</em>

<em>3 {x}^{2}  - 9 {x}^{2} = 3</em>

<em>So</em><em> </em><em>you</em><em> </em><em>will</em><em> </em><em>subtract</em><em> </em><em>9</em><em>x</em><em>²</em><em> </em><em>from</em><em> </em><em>3</em><em>x</em><em>²</em><em> </em><em>which</em><em> </em><em>won't </em><em>be</em><em> </em><em>possible </em><em>so</em><em> </em><em>it </em><em>will</em><em> </em><em>be</em><em> </em><em>negative</em><em>.</em>

<em>- 6 {x}^{2} = 3</em>

<em>Then</em><em> </em><em>you </em><em>will</em><em> </em><em>square</em><em> </em><em>root</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>making</em><em> </em><em>it</em><em>;</em>

<em>- \sqrt{6 {x}^{2} } =  \sqrt{3}</em>

<em>So</em><em> </em><em>the</em><em> </em><em>²</em><em> </em><em>will</em><em> </em><em>cancel</em><em> </em><em>the</em><em> </em><em>√</em><em> </em><em>leaving </em>

<em>-6x</em><em>=</em><em>√</em><em>3</em>

<em>-6x</em><em>=</em><em>1</em><em>.</em><em>7</em><em>3</em><em>(</em><em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em>6</em><em>)</em>

<em>x</em><em>=</em><em>0</em><em>.</em><em>2</em><em>8</em><em>8</em>

<em>That</em><em>'s</em><em> </em><em>the</em><em> </em><em>final </em><em>answer</em><em>.</em>

Charles is going to purchase a new car that has a list price of $21,450. He is planning on trading in his good-condition 2004 Do
devlian [24]
The answer is c. 16.70% This is based on the posts I've read online regarding this problem. No solution was given.

These are the amounts you have to consider:
List price of new car - 21,450
Sales tax rate: 6.88% - 21,450 x 6.88% = 1,475.76
vehicle registration fee - 1,089
documentation fee - 124
loan term - 3 years, paid monthly. so, 36 months
interest rate - 12.28% compounded monthly. 
2004 Dodge Neon value - 6,591
trade in value - 6,591 x 80% =  5,272.80

No mention of down payment so the possible amount to be financed is: 24,138.76
The value of the traded car is only considered after the financing has been paid off.
