We can re arrange this:
(-5)*(4) * x^6 * x * x^8 * y * y^6 * z^9 * z^9
using exponent properties
we can get
-20 x^15 y^7 z^18
as our simplified answer.
You are correct! The problems that can arise with a function domain are:
- Denominators that become zero
- Even-degree roots with negative input
- Logarithms with negative or zero input
In this case, you have a denominator, and you don't have roots nor logarithms. This means that your only concern must be the denominator, specifically, it cannot be zero.
And you simply have

So, the domain of this function includes every number except 3.
Answer:

Step-by-step explanation:
we know that
The scale is 
That means
1 unit in the drawing represent 40 units in the actual
or
1 inch in the drawing represent 40 inches in the actual
step 1
Find the actual dimensions of the living room
Multiply the dimensions of the living room in the drawing by 40


step 2
Convert inches to feet
Remember that

To convert inches to feet , divide by 12
so


step 3
Find the area in square feet
Multiply the length by the width

Convert to mixed number
