Ok, think about it. What’s the definition of a irrational number? Can the number be converted to a fraction or be able to be turned into a decimal that repeats or terminates? If so your looking at a rational number. If it can’t be turned into a fraction or become a repeating or terminating decimal then your number is likely a irrational number. Hope this helps. And your number is a rational number.
Answer:
x = -19
Step-by-step explanation:
1. make parentheses disappeared using distribution law.
![- 12x - 36 - 20 + 8x = 20](https://tex.z-dn.net/?f=%20-%2012x%20-%2036%20%20-%2020%20%2B%208x%20%3D%2020)
2. sum up b numbers and x
![- 4x - 56 = 20](https://tex.z-dn.net/?f=%20-%204x%20-%2056%20%3D%2020)
3. separate x and number to two sides of the equation
![- 4x = 76](https://tex.z-dn.net/?f=%20-%204x%20%3D%2076)
4. both side divided by -4
![x = - 19](https://tex.z-dn.net/?f=x%20%3D%20%20-%2019)
