Hello!
Answer:

Step-by-step explanation:
Distributive property: →→ a(b+c)=ab+ac
Order of operations stands for:
↓
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
*Left to right*
Please Excuse My Dear Aunt Sally!
First, you remove parenthesis.
6j+8j+5+5
Then, you add by the numbers from left to right.
6+8=14
14j+5+5
5+5=10
<u><em>14j+10 is the final answer.</em></u>
Hope this helps!
Have a nice day! :)

Answer:
A) 
B) 
C) for n = 2
= 1
for n = 3
= 3
for n = 4
= 8
for n = 5
= 19
Step-by-step explanation:
A) A recurrence relation for the number of bit strings of length n that contain a pair of consecutive Os can be represented below
if a string (n ) ends with 00 for n-2 positions there are a pair of consecutive Os therefore there will be :
strings
therefore for n ≥ 2
The recurrence relation for the number of bit strings of length 'n' that contains consecutive Os
b ) The initial conditions
The initial conditions are : 
C) The number of bit strings of length seven containing two consecutive 0s
here we apply the re occurrence relation and the initial conditions
for n = 2
= 1
for n = 3
= 3
for n = 4
= 8
for n = 5
= 19
