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.
12 1/4 - 3 3/5 =
49/4 - 18/5 =
245/20 - 72/20 =

Answer:
Do you want the derivative?!
Answer:
x = 17/2 = 8.500
Step-by-step explanation:
Equation at the end of step 1 :
2 • (x - 5) - 7 = 0
Step 2 :
Equation at the end of step 2 :
2x - 17 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : 2x-17 = 0
Add 17 to both sides of the equation :
2x = 17
Divide both sides of the equation by 2:
x = 17/2 = 8.500
The factored form of an equation is done by rewriting the equation in simpler forms.
The completely factored form of
is 
The expression is given as:

Factor out x from the expression, 

Express 64 as 8^2

Express the expression as a difference of two squares

Hence, the completely factored form of
is
