Answer:

Assuming you are using the zero product property, x = 2, √(3), -√(3)

Step-by-step explanation:

first I factored the (2x^2-7+1) into 2(x^2 - 3)

I also factored the (3x-6) into 3(x - 2)

Now I have the equation 6(x - 2)(x^2 - 3) = 0

I'll start with the easiest one, which is x - 2 = 0, which gives me 2

Now I solve for x^2 - 3 = 0, and I end up with two answers:

√(3) and -√(3)

So in total, x as 3 answers

Answer:

$\frac{m \times n}{100}$

Step-by-step explanation:

The value in $100=m$

The value in $1=\frac{m}{100}$

The value in $n=\frac{m \times n}{100}$

Write an equation for an ellipse centered at the origin, which has foci at (0,\pm\sqrt{63})(0,± 63 )left parenthesis, 0, comma

steposvetlana [31]

Answer:

$\frac{x^{2} }{4312 } + \frac{y^{2} }{8281 }$

Step-by-step explanation:

Since the foci are at(0,±c) = (0,±63) and vertices (0,±a) = (0,±91), the major axis is the y- axis. So, we have the equation in the form (with center at the origin) $\frac{x^{2} }{b^{2} } + \frac{y^{2} }{a^{2} }$ .

We find the co-vertices b from b = ±√(a² - c²) where a = 91 and c = 63

b = ±√(a² - c²)

= ±√(91² - 63²)

= ±√(8281 - 3969)

= ±√4312

= ±14√22

So the equation is

$\frac{x^{2} }{(14\sqrt{22}) ^{2} } + \frac{y^{2} }{91^{2} } = \frac{x^{2} }{4312 } + \frac{y^{2} }{8281 }$

Ray Of Light [21]

<h3>Total approximately 16 boxes of flooring will be needed in Stanley's living room. </h3>

Step-by-step explanation:

Here the given question is <u>incomplete</u>.

Stanley is having wood flooring installed in his living room. The installer has used 10 1/2 boxes of flooring on 2/3 of the room. How many total boxes of flooring will be needed for Stanley's living room?

The number of boxes used in the two third of room = $10 (\frac{1}{2} ) = 10.5$ boxes
