Given the numerical expression:
20i + 5i
Solution:
In order to solve the numerical expression, simply add the two numbers together since they both have a common variable i, for cases that they don't have a common variable, for example the other number exhibits the variable x, instead of i, therefore we cannot add the two numbers together. In our case, we can directly add the numbers.
= 20i + 5i
= 25i
Final answer: b. 25i
