Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:
(x-5)*(x+5)
Step-by-step explanation:
= x^2 + 5x - 25 - 5x
= x^2 +5x - 5x -25
because +5x - 5x = 0 so
= x^2 + 0 - 25
= x^2 - 25
25 can be written as 5^2
= x^2 - 5^2
we know that a^2 - b^2 = (a-b) * (a+b)
so x^2 - 5^2
= (x-5) * (x+5)

You have the function v(x) = 8(x − 1), where x <span>is the number of days since opening.
</span><span>On the first day, there will be a ceremony with 32 people in attendance.
Therefore, keeping the information above on mind, the </span><span>function that shows total visitors, including the ceremony is:
f(x)=8(x-1)+32
So, as you can see, the answer is:
</span>
f(x)=8(x-1)+32
