The correct answer would be the third option. <span>The first equation can be multiplied by –12 and the second equation by 5 to eliminate x. Calculations are as follows:

</span>-12(5x + 13y = 232)
<span>5(12x + 7y = 218)
</span>
-60<span>x - 156y =-2784
</span>60<span>x + 35y =1090
</span>
<span>Adding the two equations, we obtain the value of y.
</span>-121y = -1694
y = 14

Answer: D) (x+1)(x + 2)(x-3)

This is because the roots are x = -1, x = -2 and x = 3
Simply get all the numbers to each side to have 0 on the right side

x = -1 turns into x+1 = 0
x = -2 turns into x+2 = 0
x = 3 turns into x-3 = 0

The three factors are (x+1), (x+2) and (x-3)
Which leads to (x+1)(x+2)(x-3)

Minchanka [31]

Answer:

Step-by-step explanation:

What is a regular tessellation?

A regular tessellation is a pattern made by repeating a regular polygon. In simpler words regular tessellations are made up entirely of congruent regular polygons all meeting vertex to vertex.

How many regular tessellation are possible?

There are only 3 regular tessellation.

1. Triangle

2. Square

3. Hexagon

Why aren't there infinitely many regular tessellations?

Not more than 3 regular tessellations are possible because the sums of the interior angles are either greater than or less than 360 degrees....
