Answer:
A) −3(x3+2x−1)
Step-by-step explanation:
Factor 3-3x^3-6x to get −3(x3+2x−1)
2. A exponential decay because it is decreasing by 4. 64÷4= 16 16÷4= 4 4÷4=1
3. Neither because it is arithmetic
12m right? If I'm not mistaken you would add the number and ad on the variable afterwards.
The perimeter of a polygon or any shape is just the sum of all of its sides. If you are asked to find the perimeter of a polygon, you would simply just add all the sides together. For example, if a square has 4 sides with the length 2m, the perimeter of that square would be 2m + 2m + 2m + 2m = 8m. Perimeter just means add all the sides.
