Answer:
x = 9.0
Step-by-step explanation:
Answer: 0.1x - 16 (c)
Explanation: The perimeter is the sum of all three sides of the triangle. Since the three side are 0.5x + 9, 3x, and (-3.4x) - 25, the sum is as follows:
0.5x + 9 + 3x + (-3.4x) - 25 = 0.1x - 16
I think the answer is one of them. BOOM, MIND BLOWN!
Question:
Solution:
Let the following equation:
![\sqrt[]{12-x}=\text{ x}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B12-x%7D%3D%5Ctext%7B%20x%7D)
this is equivalent to:
![(\sqrt[]{12-x})^2=x^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B%5D%7B12-x%7D%29%5E2%3Dx%5E2)
this is equivalent to:
![12-x=x^2](https://tex.z-dn.net/?f=12-x%3Dx%5E2)
this is equivalent to:
![x^2+x-12=\text{ 0}](https://tex.z-dn.net/?f=x%5E2%2Bx-12%3D%5Ctext%7B%200%7D)
thus, we can conclude that
x= 3.
The numbers on the top depend on how many sides a dice has. Hope this helps.
