Description

Hello,

do not care about the wrong answers that I wrote, i just i did not study for the exam. Remember, all i need is just steps with more detailed answers for each one, i want to understand the questions because there will be the same exam in future. Our instructor needs not just answers, but detailed and steps answers for each question.


Number 1 ( A, B ,C D) he needs the answers + why is it the right answer. ( if there is an example that would be great)

Number 2 ( A, B C , D) I really need to understand them, so please make it more clear in steps.

Number 3( A, B) as you see it in the question, the steps for solving these problems.

Number 4 also the same and how i get the lowercase letter for the G.

Number 5 ( A, B) also i need to understand them in steps.

The most important thing to me is to understand these answers in your explanations when you write the answers in order.

Thank you my friend.
