stepladder [879]

Answer:

$7,2 ≈ D$

Step-by-step explanation:

We need to use the Distance Formula:

$\sqrt{(-x_{1} + x_{2})^{2} + (-y_{1} + y_{2})^{2}} = D \\ \\ \sqrt{(-5 + 9)^{2} + (2 + 4)^{2}} = D \\ \\ \sqrt{{4}^{2} + {6}^{2}} = D \\ \\ \sqrt{16 + 36} = D \\ \\ 2\sqrt{13} = D \\ \\ 7,2 ≈ D$

** Since we are talking about distance, we ONLY want the NON-NEGATIVE root.

A polynomial is shown below.

choli [55]

Simplified form of polynomial $3x^2-x^2+y-2y+y^2$ is $2x^2-y+y^2$

Option C is correct.

Step-by-step explanation:

The polynomial given is:

$3x^2-x^2+y-2y+y^2$

We need to write it in simplified form.

For simplifying polynomial we will combine the like terms and add them.

$3x^2-x^2+y-2y+y^2\\Combining\,\,like\,\,terms:\\(3x^2-x^2)+(y+-2y)+y^2\\(2x^2)+(-y)+y^2\\2x^2-y+y^2$

So, simplified form of polynomial $3x^2-x^2+y-2y+y^2$ is $2x^2-y+y^2$

Option C is correct.
