a square red rug has a purple square in the center. the side length of the purple square is x inches. the width of the red band

Bumek [7]

Answer:

Area of red band is $(20x + 100) inch^{2}$

Step-by-step explanation:

We know that area of square = $side^{2}$

Please refer to the attached figure, we have to calculate the area of red band.

Required area = Area of square <em>ABCD </em>- Area of <em>purple square </em>

Side of purple square = $x$

So, area of purple square = $x^{2}$

<em>ABCD </em>is a square with purple square at the center and there is symmetry in the figure.

So, width of red band towards both the end is 5 inches.

$\Rightarrow \text{side of }ABCD = 5 + 5 +x = (x+10) inches$

Required area = $(x+10)^{2} - x^{2}$

Using formula $a^{2} - b^{2} = (a-b)\times (a+b)$

$\Rightarrow (x+10-x)(x+10+x)\\\Rightarrow (10)(2x+10)\\\Rightarrow (20x+100)$

Hence, Area of red band is $(20x + 100) inch^{2}$

Answer:

x:2x:√3x.

Step-by-step explanation:

I would write it as x:2x:√3x.

The hypotenuse is twice the length of the shorter leg and the longer leg is the square root of 3 times the shorter leg.

Answer:

(2, 3)

Step-by-step explanation:

Compare the given equation ...

y = (x -2)^2 +3

to the vertex form ...

y = (x -h)^2 +k

You can see that h=2 and k=3.

The vertex of the parabola is (h, k) = (2, 3).
