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:
x1=8 x2=-8
Step-by-step explanation:
since there is absolute , means any number inside that has negative value will become positive. so the answer is -8 and 8
sorry late reply :(
3+3+3+4+4+5+6+6+7+9+9=59
59/11=5.36
so your mean is 5.36
Answer:
52
Step-by-step explanation:
Answer:
The value of A is 5
Step-by-step explanation:
- The number is divisible by 3 if the sum of its digits is a number
divisible by 3
- Ex: 126 is divisible by 3 because the sum of its digits = 1 + 2 + 3 = 6
and 6 is divisible by 3
- The number is divisible by 5 if its ones digit is zero or 5
- Ex: 675 is divisible by 5 because its ones digit is 5
890 is divisible by 5 because its ones digit is 0
- We are looking for the value of A in the 4-digit number 3A5A which
makes the number divisible by both 3 and 5
∵ A is in the ones position
∴ A must be zero or 5
- Let us try A = 0
∵ A = 0
∴ The number is 3050
∵ The sum of the digits of the number = 3 + 0 + 5 + 0 = 8
∵ 8 is not divisible by 3
∴ 3050 is not divisible by both 3 and 5
∴ A can not be zero
- Let us try A = 5
∵ A = 5
∴ The number is 3555
∵ The sum of the digits of the number = 3 + 5 + 5 + 5 = 18
∵ 18 is divisible by 3
∴ 3555 is divisible by both 3 and 5
∴ A must be equal 5
* <em>The value of A is 5</em>
