For a regular tessellation, the shapes can be duplicated infinitely to fill a plane such that there is no gap. The only shapes that can form regular tessellations are equilateral traingle(all sides are equal. This means that it can be turned to any side and it would remain the same), square and regular hexagon. Looking at the given options, we have

Octagon No

Hexagon Yes

Pentagon No

Square Yes

Triangle No(unless it is specified that it is an equilateral triangle)

Delicious77 [7]

I got 27.5 for the mean
mean: you add up all the #'s and divide them my their quantity( in other words by how many numbers there are)
In your case you have 8 numbers, you add them and divide them by 8!

Hope it helps ;)

Solve y

Ksivusya [100]

The value of y in $-3 = 7\left(y-\dfrac97\right)$ is 6/7

<h3>How to solve for y?</h3>

The equation is given as:

$-3 = 7\left(y-\dfrac97\right)$

Open the bracket

-3 = 7y - 9

Add 9 to both sides of the equation

7y = 6

Divide both sides by 7

y= 6/7

Hence, the value of y in $-3 = 7\left(y-\dfrac97\right)$ is 6/7
