Prompt (Word-for-word): "By factoring the numerator and denominator simplify the following rational expressions as much as possible and write your final answer as a single reduced fraction."

The first image is the question I was having trouble with and the second image is my work and final answer. I feel a little uncertain of it and I just want to know if I did it correctly. If I didn't then please let me know. This isn't just homework it's also review for an exam so I need to know if I'm doing this right.

I'm following instructions for a science project but immediately ran into a big issue due to the tutorial being on an ancient version of Excel (2003) I was able to find the format axis by clicking the X axis on my graph but couldn't find the scale option. Help please

Can someone help me with these drawings? I’ve just started and I’m not sure if I’m doing it right—AI keeps getting it wrong—so I’d really appreciate the help. The task involves drawing the missing projection: for 423, it’s the top view, and for 424, it’s the side view. If it’s not too much trouble, could you also explain the reasoning behind it? I’d be very grateful for any help.

In addition to the task itself, I also added how I drew it, just in case these drawings are drawn according to European standards.
