Answer:
![x(x+5)=x^2-3x+8](https://tex.z-dn.net/?f=x%28x%2B5%29%3Dx%5E2-3x%2B8)
Step-by-step explanation:
There are infinite cases of equations with exactly one real solution. To create something worth the space, this one should suffice
![x(x+5)=x^2-3x+8](https://tex.z-dn.net/?f=x%28x%2B5%29%3Dx%5E2-3x%2B8)
Operating
![x^2+5x=x^2-3x+8](https://tex.z-dn.net/?f=x%5E2%2B5x%3Dx%5E2-3x%2B8)
Simplifying
![5x=-3x+8](https://tex.z-dn.net/?f=5x%3D-3x%2B8)
Joining like terms
![8x=8](https://tex.z-dn.net/?f=8x%3D8)
Solving
x=1
Testing the result
![1(1+5)=1^2-3(1)+8=>6=6](https://tex.z-dn.net/?f=1%281%2B5%29%3D1%5E2-3%281%29%2B8%3D%3E6%3D6)
Answer:
180 Square Feet
Step-by-step explanation:
For Rectangle:
l = 9 ft
b = 20 ft
Area of Rectangle
![= l \times b \\ = 9 \times 20 \\ = 180 \:square \: feet](https://tex.z-dn.net/?f=%20%3D%20l%20%5Ctimes%20b%20%5C%5C%20%20%3D%209%20%5Ctimes%2020%20%5C%5C%20%20%3D%20180%20%5C%3Asquare%20%5C%3A%20%20feet)
The answer is B. 7 times a number plus 4 would be 7n +4.
