Answer:
80 in.
Step-by-step explanation:
to find the perimeter of a shape you add all of the side lengths together
20+20+20+20
Answer:
84% or 21/25
Step-by-step explanation:
1 is 8, 2 is 6, 3 is 9, 4 is 11, 5 is 9, 6 is 7. add the values: We get 50.
because landing on 1 is an 8/50 chance, not landing on one is a 42/50 chance, which in turn is 84% or 21/25.
I believe the correct answer is A,
There are 6 other positions in the string, each with 26 choices. So if you fix BO as the first two letters, there are

possible strings that you can make.
If BO is at the end of the string, you still have

possible strings.
Together, then, you have

possible strings.
