Answer:

x = 3

Step-by-step explanation:

the axis of symmetry is a vertical line passing throught the vertex with equation

x = c ( where c is the value of the x- coordinate of the vertex )

vertex has coordinates (3, - 1 ) with x- coordinate 3 , then

equation of axis of symmetry is x = 3

Answer:

13 - 17 $\sqrt{11}$

Step-by-step explanation:

Using the rule

$\sqrt{a}$ × $\sqrt{a}$ = a

Each term in the second factor is multiplied by each term in the first factor, that is

2 $\sqrt{11}$ ( $\sqrt{11}$ - 9 ) + 1 ( $\sqrt{11}$ - 9 )

Distribute both parenthesis

= (2 × 11) - 18 $\sqrt{11}$ + $\sqrt{11}$ - 9

= 22 - 17 $\sqrt{11}$ - 9

= 13 - 17 $\sqrt{11}$

a square has a side length of x. A rectangle has a length that is 4 inches longer than the square and a width that is 2 inches s

vodomira [7]

Answer:

Length of the rectangle is = 8 inches.

Step-by-step explanation:

Given :

Area of square = Area of the rectangle

According to the question:

Length of the square be 'x'.

Its area = (Side)*(Side) = $x^2$ ...equation (i)

Length of the rectangle = $(x+4)$

Width of the rectangle = $(x-2)$

Area of the rectangle =Length * Width

⇒ $(x+4)(x-2)=x^2-2x+4x-8$

⇒ $x^2+2x-8$ ...equation (ii)

Equating both the equation as area of both the figure are equal.

⇒ $x^2+2x-8=x^2$

⇒ $2x-8=0$ ...subtracting $x^2$ both sides

⇒ $2x=8$ ...dividing both sides with 2

⇒ $x=\frac{8}{2}=4$ inches

Plugging the value of x=4 in the length of the rectangle.

We have,

⇒ $(x+4)=(4+4)=8$

So the length of the rectangle = 8 inches.
