Please help, will give brainliest and thanks :) Please attach any thing if needed.
Dmitry_Shevchenko [17]

Answer:

First of all, I expect you fulfill your word and give what you promise... ha ha just kidding, I already solved a question like this one, please see below explanation.

1. Tessellation is the covering of a surface with pattern(s) of flat shapes so that there are no overlaps or gaps. It is also called Tiling.

2. Triangles, Squares, and Hexagons are regular polygons.

3. Previous three shapes create a regular tessellation pattern because all their sides and all their angles are the same. the intersection point of the interior angles is called "Vertex". For a regular tessellation, the pattern is identical at each Vertex.

Unlike the triangle and quadrilateral case, the Pentagon's angle sum of 540° is not helpful when trying to fit a bunch of Pentagons around a vertex. Therefore, even though the Pentagon is a regular polygon, it cannot tessellate.

4. See attached screenshot of 3 tessellations created with Tessellation Artist Software online.

Factor each completely <br> 5n^2-8n-21<br> 6r^2+53r-79<br> 4n^2-25
OLEGan [10]

5n² - 8n - 21    →    (5)(- 21) = -105    (find 2 numbers whose product is 105 and sum is -8)

= 5n² - 15n  + 7n - 21

= 5n(n - 3)  + 7(n - 3)

= (5n + 7)(n - 3)

*****************************************************

6n² + 53n - 79 → (6)( -79) = -474 (find 2 numbers whose product is -474 and sum is 53)  DOES NOT EXIST! only factors are: (1, 474) (2, 237) (3, 158) (6, 79)

= Prime

*******************************************************

4n² - 25   (this is the difference of two squares)

= √(4n²) +/- √(25)

= 2n +/- 5

= (2n + 5)(2n - 5)

Korey and lan are arguing about how to find the perimeter of a rectangle. Korey says you should add the length and the width and
weqwewe [10]
I would say Korey because let’s say you have a rectangle and two sides are 2 and the other two sides are 5. Well if you add 5 + 2 which equals 7 times 2 equals 14, you get the same answer as you would if you added everything
