Answer:
<u>Part A</u>

Applying Distributive property: 
<u>Part B</u>

Step-by-step explanation:
<em><u> Attached is the model that belongs to this exercise (The model was missing)</u></em>
The formula for calculate the area of a rectangle is:

Where "l" is the lenght and "w" is the width.
<u>Part A</u>
Notice that the dimensions of the new bathroom are:

We do not know the width of the new bathroom, but we know that both rooms will have the same length. Knowing this, we can write an expression for the total area of both rooms by using the Distributive Property:

Applying Distributive property:
<u>Part B</u>
If the width of the bedroom is 18 feet, you need to substitute this value into the expression
in order to find the total square footage of the two rooms:

Answer:
95
Step-by-step explanation:
The smallest number that divided by 6, 15, and 18 leavses 5 in each case is 95
Answer:
-2
Step-by-step explanation:

Therefore, the average rate of change over the interval [-4,-1] is -2.
First, find the mean. You'll need it to compute the variance.

The variance of the sample is then computed with the formula

The standard deviation is the square root of the variance, so
