MPLIFIES THE EXPRESSION?
1 answer:
Answer:
The coefficient of x is 8
Step-by-step explanation:
Given
--- Perimeter
Required
Determine the coefficient of x
![P = 2(x+8) + 2(3x)](https://tex.z-dn.net/?f=P%20%3D%202%28x%2B8%29%20%2B%202%283x%29)
Open bracket
![P = 2x + 16 + 6x](https://tex.z-dn.net/?f=P%20%3D%202x%20%2B%2016%20%2B%206x)
Collect like terms
![P = 2x + 6x+ 16](https://tex.z-dn.net/?f=P%20%3D%202x%20%2B%206x%2B%2016)
![P = 8x+ 16](https://tex.z-dn.net/?f=P%20%3D%208x%2B%2016)
<em>The coefficient of x is 8</em>
