Find the distance between the two points.
Law Incorporation [45]

Answer:  89 will go in the box

This means the exact distance between the two given points is \sqrt{89} which approximates to roughly 9.4339811

===========================================================

Explanation:

To get that answer, we can apply the distance formula

(x1,y1) = (-1,-5) is the first point

(x2,y2) = (4,3) is the second point

Plug the coordinates into the distance formula

d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-1-4)^2 + (-5-3)^2}\\\\d = \sqrt{(-5)^2 + (-8)^2}\\\\d = \sqrt{25 + 64}\\\\d = \sqrt{89}\\\\d \approx 9.4339811\\\\

--------------------------

Alternative Method:

You could also form a right triangle by adding the point (4, -5). The horizontal leg goes from (-1,-5) to (4,-5) which is a span of 5 units. The vertical leg goes from (4,-5) to (4,3) which is a span of 8 units. The hypotenuse is from (-1,-5) to (4,3) which is the distance we want to find.

After forming the triangle and determining the leg lengths, use the pythagorean theorem and you should get \sqrt{89} as the length of the hypotenuse. As you can probably guess, the distance formula is effectively a slight rephrasing the pythagorean theorem.

Factor completely. -2k - k3^ - 3k^2
wlad13 [49]

Answer:

-k(k+1)(k+2)

Step-by-step explanation:

Begin to factor by using GCF by finding the greatest common factor. Here it is k.

-2k-k^3-3k^2 = -k(2+k^2+3k)

We will rearrange and factor the trinomial.

-k(2+k^2+3k)\\-k(k^2+3k+2)\\-k(k+1)(k+2)
