Answer:
x = 20
Step-by-step explanation:
given f(x) = 
, we have to solve
= 4
Square both sides
()² = 4²
x - 4 = 16 ( add 4 to both sides )
x = 20
As a check
= 
= 4 ← correct

Answer in explanation
Step-by-step explanation:
When we talk of compression of gases, what we are talking about is simply the reduction in the volume of the gases. When we compress a volume of a gas, we are looking at reducing the volume of the gas in question.
Now, let’s work through this. The postulate that works in this scenario is that postulate about the interaction between the gas molecules whether attractive or repulsive are negligible. This is the driving force that dictates the compressibility of gases.
Gases are termed compressible because the the negligible force of attraction or repulsion between them confers a kind of fluidity to these gases. It is this fluidity that makes it possible for gases to be compressible.
If it was that the attractive or repulsive forces are not negligible, they would have posed a difficulty that would be dependent on the strength of the compressive forces to overcome
b² + 6b - 16 = 0
b² + 8b - 2b - 16 = 0
b(b) + b(8) - 2(b) - 2(8) = 0
b(b + 8) - 2(b + 8) = 0
(b - 2)(b + 8) = 0
b - 2 = 0 or b + 8 = 0
<u> + 2 + 2</u> <u> - 8 - 8</u>
b = 2 b = -8
Not at all, I was doing online school before quarantine started, so this is all normal for me lol

Step-by-step explanation:
We are given that John is building a rectangular pen for his sheep.\
We have to complete the given equation
Let w be the width of rectangular pen
According to question
Length of pen=8w+5
We know that
Area of rectangle=
Using the formula
Area of rectangular pen=
Therefore, the area of rectangular pen=A=
