The value of (f - g)(x) is -x - 14
<h3>How to evaluate the function?</h3>
The given parameters are:
f(x) = 4x - 8
g(x) = 5x + 6
To calculate (f - g)(x), we make use of
(f - g)(x) = f(x) - g(x)
So, we have:
(f - g)(x) = 4x - 8 - 5x - 6
Evaluate the like terms
(f - g)(x) = -x - 14
Hence, the value of (f - g)(x) is -x - 14

Step-by-step explanation:
A playing card is in the form of a rectangle whose perimeter is equal to 28 cm and area is 45 cm².
If l and b are length and breadth of the rectangle.
Area,
![A=lb](https://tex.z-dn.net/?f=A%3Dlb)
![45=lb\\\\l=\dfrac{45}{b}\ .....(1)](https://tex.z-dn.net/?f=45%3Dlb%5C%5C%5C%5Cl%3D%5Cdfrac%7B45%7D%7Bb%7D%5C%20.....%281%29)
Perimeter,
![P=2(l+b)\\\\28=2(l+b)\\\\14=(l+b)\ ....(2)](https://tex.z-dn.net/?f=P%3D2%28l%2Bb%29%5C%5C%5C%5C28%3D2%28l%2Bb%29%5C%5C%5C%5C14%3D%28l%2Bb%29%5C%20....%282%29)
Put the value of l from equation (1) to equation (2). So,
![14=\dfrac{45}{b}+b\\\\14=\dfrac{45+b^2}{b}\\\\14b=45+b^2\\\\b^2-14b+45=0\\\\b^2-9b-5b+45=0\\\\b(b-9)-5(b-9)=0\\\\b=5\ cm, 9\ cm](https://tex.z-dn.net/?f=14%3D%5Cdfrac%7B45%7D%7Bb%7D%2Bb%5C%5C%5C%5C14%3D%5Cdfrac%7B45%2Bb%5E2%7D%7Bb%7D%5C%5C%5C%5C14b%3D45%2Bb%5E2%5C%5C%5C%5Cb%5E2-14b%2B45%3D0%5C%5C%5C%5Cb%5E2-9b-5b%2B45%3D0%5C%5C%5C%5Cb%28b-9%29-5%28b-9%29%3D0%5C%5C%5C%5Cb%3D5%5C%20cm%2C%209%5C%20cm)
Put the value of b in equation (1),
If b = 5 cm
![l=\dfrac{45}{5}=9\ cm](https://tex.z-dn.net/?f=l%3D%5Cdfrac%7B45%7D%7B5%7D%3D9%5C%20cm)
If b = 9 cm
![l=\dfrac{45}{9}=5\ cm](https://tex.z-dn.net/?f=l%3D%5Cdfrac%7B45%7D%7B9%7D%3D5%5C%20cm)
So, the dimensions of the playing card is 9 cm by 5 cm.
