Answer:

2644.415 feet spuared

Step-by-step explanation:

I think the attached photo is your full question, and my answer:

We need to find:

- the area of the  pool = πr^{2} = 3.14* 20.5^{2} = 1319.585 feet spuared.

- The area of the triangular fence = 1/2* 84*92 = 3964 feet spuared

So, the area of the backyard which is not covered by the pool is:

<em>The area of the triangular fence - the area of the  pool</em>

= 3964 - 1319.585

= 2644.415

Hope it will find you well.

Solve x2 + 6x + 7 = 0. (2 points)
Alexandra [31]

Option C: $x=-3 \pm\sqrt{2}

Solution:

Given equation is x^{2}+6 x+7=0.

This is a quadratic equation.

Here a = 1, b = 6, c = 7

To solve the given equation by quadratic formula,

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}

Substitute the given values in the quadratic formula, we get

$x=\frac{-6 \pm \sqrt{6^{2}-4 (1) (7)}}{2 (1)}

$x=\frac{-6 \pm \sqrt{36-28}}{2 }

$x=\frac{-6 \pm \sqrt{8}}{2 }

$x=\frac{-6 \pm2 \sqrt{2}}{2 }

$x=\frac{2(-3 \pm\sqrt{2})}{2 }

2 in the numerator and denominator are cancelled.

$x=-3 \pm\sqrt{2}

Option C is the correct answer.
