Answer:

$\large\boxed{\sf \ \ x = 3+\sqrt{11} \ \ or \ \ x = 3-\sqrt{11} \ \ }$

Step-by-step explanation:

Hello,

$x^2-6x+9=11\\ x^2-2*3*x+3^2=11\\(x-3)^2=11\\ x-3=\sqrt{11} \ or \ x-3=-\sqrt{11}\\ x = 3+\sqrt{11} \ or \ x = 3-\sqrt{11}$

Do not hesitate if you have any question

Hope this helps

Answer:

x = 3 ± sqrt(11)

Step-by-step explanation:

x^2 - 6x + 9 = 11

Recognizing that this is a perfect square trinomial

(x-3) ^2 =11

Taking the square root of each side

sqrt((x-3) ^2) = ± sqrt(11)

x-3 =± sqrt(11)

Add 3 to each side

x = 3 ± sqrt(11)

The areas of the squares adjacent to two sides of a right triangle are shown below.

UkoKoshka [18]

Answer:

$85\:\mathrm{units^2}$

Step-by-step explanation:

All side lengths of a square are equal. The three squares create a right triangle, and the hypotenuse of this triangle represents the side length of the square.

All right triangles must follow the Pythagorean Theorem $a^2+b^2=c^2$ where $c$ is the hypotenuse of the triangle.

Therefore, let $h$ be the side length of this largest square. Since the area of a square with side length $s$ is given by $s^2$ , $h^2$ will represent the area of the square:

$\sqrt{35}^2+\sqrt{50}^2=h^2=\boxed{85\:\mathrm{units^2}}$
