<u>Part A</u>
![A_{t}=22(12+w)](https://tex.z-dn.net/?f=A_%7Bt%7D%3D22%2812%2Bw%29)
Applying Distributive property: ![A_{t}=264+22w](https://tex.z-dn.net/?f=A_%7Bt%7D%3D264%2B22w)
<u>Part B</u>
![A_{t}=660\ ft^2](https://tex.z-dn.net/?f=A_%7Bt%7D%3D660%5C%20ft%5E2)
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:
![A=lw](https://tex.z-dn.net/?f=A%3Dlw)
Where "l" is the lenght and "w" is the width.
<u>Part A</u>
Notice that the dimensions of the new bathroom are:
![l=22\ ft\\w=12\ ft](https://tex.z-dn.net/?f=l%3D22%5C%20ft%5C%5Cw%3D12%5C%20ft)
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:
![A_{t}=22(12+w)](https://tex.z-dn.net/?f=A_%7Bt%7D%3D22%2812%2Bw%29)
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:
![A_{t}=264+22w\\\\A_{t}=660\ ft^2](https://tex.z-dn.net/?f=A_%7Bt%7D%3D264%2B22w%5C%5C%5C%5CA_%7Bt%7D%3D660%5C%20ft%5E2)
Answer: <em>$6,400</em>
Step-by-step explanation:
<em>First, let's take the given numbers</em>
<em>Starts the account with $1600</em>
<em>Deposits $200 each week after opening it</em>
<em>25 weeks</em>
<em>We can't count the first week because it says "thereafter"</em>
<em>So we need to do 24x200</em>
<em>which is 4,800</em>
<em>Now we must add the original amount deposited and the amount of money added in 25 weeks</em>
<em>1,600+4,800</em>
<em>$6,400</em>
Answer:
![tan(a)=\frac{opposite}{adjacent}](https://tex.z-dn.net/?f=tan%28a%29%3D%5Cfrac%7Bopposite%7D%7Badjacent%7D)
Step-by-step explanation:
In a right triangle, the side adjacent angle a is 12, the
hypotenuse is 24.
Angle 'a' is 12
hypotenuse is 24
![sin(a)=\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sin%28a%29%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
![sin(12)=\frac{opposite}{24}](https://tex.z-dn.net/?f=sin%2812%29%3D%5Cfrac%7Bopposite%7D%7B24%7D)
opposite side = 24 times sin(12)=5
![cos(a)=\frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=cos%28a%29%3D%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D)
![cos(12)=\frac{adjacent}{24}](https://tex.z-dn.net/?f=cos%2812%29%3D%5Cfrac%7Badjacent%7D%7B24%7D)
adjacent side = 24 times cos(12)=23.5
![tan(a)=\frac{opposite}{adjacent}](https://tex.z-dn.net/?f=tan%28a%29%3D%5Cfrac%7Bopposite%7D%7Badjacent%7D)
![tan(a)=\frac{5}{23.5}](https://tex.z-dn.net/?f=tan%28a%29%3D%5Cfrac%7B5%7D%7B23.5%7D)
