First, work out the difference(increase) between the two numbers you are comparing. So, the difference would be <em>100-80</em>, which will equal <em>20</em>.
Then, divide the increase by the original number and multiply the answer by 100. So, that would be <em>20÷100</em>, which would be <em>0.2</em>, then it would be <em>0.2⋅100</em>, so back to <em>20</em>.
The percent of increase should be 20.
Answer:
Not a factor because there is a remainder.
Step-by-step explanation:
Let's use synthetic division to solve this..
-1 ║ 2 | 4 | -2 | -8
║ | -2| -2 | 4
║ 2 | 2| -4 | -4
PS: if anyone knows a better way to do a synthetic division chart please let me know.
Trapezoid since the sides are the same but the top and bottom are not
