Which course is this for? I feel like I may need a little more information, but the simplest explanation I can give given the question is:
<em>f(x)</em> is the value of a function <em>f</em> evaluated at the value <em>x</em>. The formal definition of a function is a particular set of rules that associates a particular value with another. For an analogy: you can think of <em>f </em>as a machine that takes in an input, transforms it according to a certain set of rules, and produces an output. <em />In this analogy, <em>x</em> would be the input and <em>f(x)</em> would be the output.

Answer:
B. Every 16 minutes, 22 more pizzas were set out on the buffet.
Step-by-step explanation:
At 11:00 am, x would be equal to 0, and there would be 15 pizzas on the buffet line. Then, every 8 minutes, 11 more pizzas are added to the buffet line. So in 16 minutes, 22 pizzas will be added to the buffet.

Answer:
The other factor is (x + 2).
Step-by-step explanation:
If x - 10 is a factor of x^2 - 8x - 20 then we must find another factor that includes +2x, so that we have -10x + 2x = -8x. That factor is (x + 2):
x^2 - 8x - 20 = (x - 10)(x + 2)
As a test, multiply -10 and +2. We get -20, matching the constant of the given polynomial. Also, -10x + 2x = -8x, another match.
<span>A = Area
L= Length = 15
W + widith = 10
A = 150
The pool area is
L = 10
w= 5
A= 50
So the area of the perimeter = 100 square meters</span>
