Rigid Transformations:Question 9 Select all symmetry present in the following shape.
Choose all that apply:
No Symmetry
90-degree Rotational Symmetry
180-degree Rotational Symmetry
Reflectional Symmetry

I would say Reflectional Symmetry but I don't know the shapes since you didn't show them here.

Step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
