3. There is only one at 360 degrees
4. there are 6 rotational symmetries and the number of reflectional symmetries would be 6 as you can see:
Answer:
Step-by-step explanation:

First, on the right-hand side of the equation, let's distribute the
to each term in the parenthesis:

Now, let's move all the terms with an
to the left-hand side, and everything else to the right-hand side of the equation:

Let's combine like terms:

Finally, let's divide each side by
to get
by itself on the left-hand side of the equation:

Hey You!
The two are related because they both use the same three numbers. For example:
6 × 3 = 18 3 × 6 = 18
Or,
18 ÷ 3 = 6 18 ÷ 6 = 3
Answer:
(9+g)/f
Step-by-step explanation:
First you add 9 and g then it says "then divide f by the result" so it would come after addition and you have to divide the result by f so addition comes first so you should use () and put a division symbol by f
