expression represents the area of Dylan’s room
<h3><u>
Solution:</u></h3>
Given that,
Length of room = ![x^2 -2x+8](https://tex.z-dn.net/?f=x%5E2%20-2x%2B8)
Width of room = ![2x^2 + 5x - 7](https://tex.z-dn.net/?f=2x%5E2%20%2B%205x%20-%207)
To find: Expression that the area (lw) of Dylan’s room
Since bedroom is generally of rectangular shape, we can use area of rectangle
<em><u>The area of rectangle is given as:</u></em>
![\text {area of rectangle }=\text { length } \times \text { width }](https://tex.z-dn.net/?f=%5Ctext%20%7Barea%20of%20rectangle%20%7D%3D%5Ctext%20%7B%20length%20%7D%20%5Ctimes%20%5Ctext%20%7B%20width%20%7D)
Substituting the given expressions of length and width,
![area = (x^2 -2x+8)(2x^2 + 5x - 7)](https://tex.z-dn.net/?f=area%20%3D%20%28x%5E2%20-2x%2B8%29%282x%5E2%20%2B%205x%20-%207%29)
We multiply each term inside first parenthesis with each term inside the second parenthesis.
So it becomes,
![2x^4 + 5x^3 - 7x^2 -4x^3 -10x^2 +14x +16x^2 +40x - 56](https://tex.z-dn.net/?f=2x%5E4%20%2B%205x%5E3%20-%207x%5E2%20-4x%5E3%20-10x%5E2%20%2B14x%20%2B16x%5E2%20%2B40x%20-%2056)
Now combine like terms,
![2x^4 + x^3 - x^2 +54x - 56](https://tex.z-dn.net/?f=2x%5E4%20%2B%20x%5E3%20-%20x%5E2%20%2B54x%20-%2056)
Thus the above expression represents the area of Dylan’s room
Answer:
Since we have the information for Angles 1 and 3, and they are vertical, we can set them equal to each other. Once we have done this we can find the measures of them combined, and subtract it from 360 in order to only have the measure of 2 and its vertical angle. Finally, all we need to do now is divide the remaining measure by 2, and this will give us the measure of angle 2.
Angle 1=Angle 3
4x+30=2x+48
2x+30=48
2x=18
x=9
Angle 1=4(9)+30
Angle 1=36+30
Angle 1=66
Angle 1=Angle 3
Angle 1+ Angle 3=132
360-132=228
228/2=114
Angle 2= 114

Step-by-step explanation:
the domain is every possible input value and the range is every possible output value. since the outputs are all positive, the range is equal to all real numbers. and since the graph starts at 1,000, the domain is greater than or equal to 1,000
