Option A:
is the area of the rectangle
Explanation:
Given that the length of the rectangle is ![2x-5](https://tex.z-dn.net/?f=2x-5)
The width of the rectangle is ![x+4](https://tex.z-dn.net/?f=x%2B4)
<u>Area of the rectangle:</u>
The area of the rectangle can be determined using the formula,
![Area = length \times width](https://tex.z-dn.net/?f=Area%20%3D%20length%20%5Ctimes%20width)
Substituting the values of length and width, we get,
![Area=(2x-5)(x+4)](https://tex.z-dn.net/?f=Area%3D%282x-5%29%28x%2B4%29)
Multiplying each term within the parenthesis, we get,
![Area=2x^{2} +8x-5x-20](https://tex.z-dn.net/?f=Area%3D2x%5E%7B2%7D%20%2B8x-5x-20)
Adding the like terms, we get,
![Area=2x^{2} +3x-20](https://tex.z-dn.net/?f=Area%3D2x%5E%7B2%7D%20%2B3x-20)
Thus, the area of the rectangle is ![2x^{2} +3x-20](https://tex.z-dn.net/?f=2x%5E%7B2%7D%20%2B3x-20)
Hence, Option A is the correct answer.
Answer:
x=(3-y)/2
y=3-2x)
Step-by-step explanation:
2x+y = 3
x=(3-y)/2
y=3-2x)
Answer:
Step-by-step explanation:
the answer to this problem is 14
Step-by-step explanation:
x²/(x²-9) + 1/(x-3) = 1/(4x-12)
4x² + 4(x+3) = 1
4x² + 4x + 11 = 0
Since the discriminant is negative, there are no real solutions.
