Answer:

$\boxed{2 {x}^{2} - 11x + 11}$

Step-by-step explanation:

$= > ( {x}^{2} - 11x + 6) + ( {x}^{2} + 5) \\ \\ = > {x}^{2} - 11x + 6 + {x}^{2} + 5 \\ \\ = > {x}^{2} + {x}^{2} - 11x + 6 + 5 \\ \\ = > 2 {x}^{2} - 11x + 11$

What is the distance between (4,2) and (-1,-3)

Sati [7]

<h2>Solving for the Distance between two Points</h2><h3>Answer:</h3>

$5 \sqrt{2}$ or $7.071$

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this Question to know more about distances between two points: <u>brainly.com/question/24629826</u></em>

Given:

$(4,2)$

$(-1,-3)$

Solving for the Distance:

$\sqrt{(4-(-1))^2 +(2 -(-3))^2} \\ \sqrt{(4 +1)^2 +(2 +3)^2} \\ \sqrt{5^2 +5^2} \\ \sqrt{25 +25} \\ \sqrt{50} \\ \sqrt{25 \cdot 2} \\ 5 \sqrt{2}$

<u>Note:</u>

$5 \sqrt{2} \approx 7.071$

I need help with ANLGES!!!!

Phantasy [73]

Answer:

32, consecutive interior angles are supplementary.

Step-by-step explanation:

We know that the two angles add up to 180, because consecutive interior angles are supplementary. So let's set up an equation equal to 180.

2x + 3x + 20 = 180

Now let's add like terms.

5x + 20 = 180

Now let's subtract 20 from both sides.

5x = 160

Now let's divide both sides by 5.

x = 32
