\frac{3}{9-\sqrt{2} } * \frac{9+\sqrt{2}}{9+\sqrt{2}}

\frac{27 + 3\sqrt{2} }{9^{2} - (\sqrt{2})^{2}  }

\frac{27 + 3 \sqrt{2} }{81 - 2}

\frac{27 + 3\sqrt{2} }{79}

A rectangle has a length of (x+10) centimeters and a width of x centimeters. If the perimeter is 32 centimeters, what is the len
I am Lyosha [343]

Given:

Length of rectangle = (x+10) cm

Width of the rectangle = x cm

Perimeter = 32 cm

To find:

The length of the rectangle.

Solution:

We know that,

Perimeter=2(l+w)

Where, l is length and w is width.

Substituting the values, we get

32=2((x+10)+x)

32=2(2x+10)

32=4x+20

Subtract 20 from both sides.

32-20=4x

12=4x

Divide both sides by

3=x

So, the length is

3+10=13

Therefore, the length of the rectangle is 13 cm.

Given the function f(x)= 14x^2 + 5x - 1 answer the question if you could change the 14 to any other number, but the rest has to
polet [3.4K]
This is a polynomial of degree 2, and remember that complex roots always come in pairs; therefore, in a second degree polynomial you can only have 0 real roots and 2 complex roots, or 2 real roots and 0 complex roots. There is no way you can have 1 real root and 1 complex root because, as stated before, complex (non-real) roots always come in pairs; so the only way of having 1 real root is dumping the polynomial of degree 2 (14 x^{2}) by changing the 14 to 0. That way we'll left with f(x)=5x-1 which only has one real root:
0=5x-1
5x=1
x= \frac{1}{5}

Can some help I’m suffering with this question
ziro4ka [17]

Answer:

38 quarters

Step-by-step explanation:

0.25 x 63 = 15.75

0.05 x 63 = 3.15

----------------------------

0.25 x 50 = 12.50

                    +         = $13.15

0.05 x 13 = 0.65

----------------------------

0.25 x 25 = 6.25

                   +        = $8.15

0.05 x 38 = 1.90

----------------------------

0.25 x 30 = 7.50

                   +         = $9.15

0.05 x 33 = 1.65

--------------------------

0.25 x 35 = 8.75

                   +        = $10.15

0.05 x 28 = 1.40

-------------------------

0.25 x 38 = 9.50

                   +        = $10.75

0.05 x 25 = 1.25

------------------------------

I hope this helps!
