Answer: 3, 4, 6

Step-by-step explanation: equilateral triangle, square, regular hexagon

In a regular tessellation 3,4,6 sides can be tessellating regular

polygon.

A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.

First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.

A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.

A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.

[tex]\frac{1}{9^{2} }[/tex]=1/81

[tex]9^{\frac{1}{2} }[/tex] =3

[tex]\frac{1^{2} }{9}[/tex]=[tex]\frac{1}{9}[/tex]

[tex]9^{-2}[/tex]=1/81

Step-by-step explanation:

Answer:

The area is multiplied by 9

Step-by-step explanation:

Since the area of a kite is the two diagonals multiplied together and then divided by two (turn the kite into two triangles if you don't believe me), then the change in area would be from x*y/2 to 3x*3y/2, which is the same as 9x*y/2, i.e. nine times the original area.

Answer:

The correct answer:  The area is multiplied by 9.

Answer:

The annual interest rate is 6%

Step-by-step explanation:

Use the formula for simple interest:  i = prt.

Set i = prt equal to $30:  $30 = prt

Solve this for r:

         $30

r = -------------- = ($30) / ($500)  = 0.06

      $250(2)

The annual interest rate is 6%

Answer:

12 quarters

Step-by-step explanation:

number of quarters ---------x

number of dimes ------------y

therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1

              0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2

equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12

there are 12 quarters

Answer:

Option C would be correct!

Step-by-step explanation:

Since,

For Option A 8(2r) would be 16r not 10r

For Option B 6r + 3 would be 6r + 3 not 9r

For Option C 9(3r - 4) would be 27r - 36, and that indeed is the answer

For Option D r + r + r + r + r would be 5r not r⁵

Answer:

8 and 5

Step-by-step explanation:

Let the number of feet added = x

(x + 6) ( x + 3) = 40               Remove the brackets

x^2 + 6x + 3x + 18 = 40        Combine like terms on the left

x^2 + 9x + 18 = 40                Subtract 18 from both sides

               -18    -18

x^2 + 9x = 22                        Subtract 22 from both sides

x^2 + 9x - 22 = 0

This quadratic factors

(x + 11)(x - 2)

x + 11 = 0

x = - 11 which makes not sense.

x - 2 = 0

x = 2

The answer is x = 2
