Factor the following trinomial. (Hint: Solve the equations first.)<br><br> x²-2x-2

Alex_Xolod [135]

Answer:

$(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2} -2x-2=0$

so

$a=1\\b=-2\\c=-2$

substitute in the formula

$x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}$

$x=\frac{2(+/-)\sqrt{12}} {2}$

$x=\frac{2(+/-)2\sqrt{3}} {2}$

$x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}$

$x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}$

therefore

$x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))$

In order to join a dance class at Dancing’s Lily’s Academy, you must pay a $335 annual fee plus $13.75 for each class you attend

Nuetrik [128]

Answer:

12

Step-by-step explanation:

335 + 13.75x = 500

Subtract 335 from each side

13.75x = 165

Divide each side by 13.75

x = 12

You can attend 12 dance classes with $500.

Uptown Cable, a cable TV provider, charges each customer $120 for installation, plus $25 per month for cable programming. Uptown

nikklg [1K]

Answer:

B) Six Months.

Step-by-step explanation:

We can write an equation to model each situtation.

Let <em>m</em> be the number of months and <em>c</em> be its total cost.

Uptown Cable charges $120 for the initial installation fee plus $25 per month. In other words, its total cost is:

$c=120+25m$

Downtown Cable charges an initial $60 fee plus $35 per month. So:

$c=60+35m$

To find after how many months will the two services remain the same, we can set the two equations equal to each other and solve for <em>m</em>. So:

$120+25m=60+35m$

Solve for <em>m: </em>

<em /> $60=10m\Rightarrow m=6$ <em />

<em />

The two cable companies will charge the same after six months of use.

Notes:

If the customer uses the service for less than six months, then Downtown Cable is better since its initial cost is lower.

If the customer uses the service for more than six months, then Uptown Cable is better since its rate per month is lower.
