2. S1 is incorrect; you are not taking the 15 there because that would be the full length, you are taking x.
S2 is correct.

6. S2: That's incorrect. You need to use brackets; do altogether which means as you distribute it into the brackets.

Good. Well we are told that the area is 138, AND we found it to be in terms of x as -3x+165. So what can we do to these two?

Yep, I want you to work on your multiplication involving some x's.

I know you can do as you've demonstrated this and it's pretty straight forward.
Try these, simplify them, make use of that multiplication table I've shown you if you think it will help

Edit: I've added spoilers where the answers are, for you to check!

Heyaa I used this method, the one I learnt in class as these questions were a bit easy
I got 1 wrong and that was because I forgot to add the power.

If they were easy then I'm surprised you were struggling with one in that question yesterday Well done.

You should mark that paper you did (unless your teacher wants it handed it to him/her), and find a new one to practice
There isn't much that I can see you need to improve on from the questions we did. Pick up a higher tier paper so you can push the D grade up or whatever level you're at. What exam board are you doing?
17. Yeah

I'm doing AQA.

19. Bearing is the angle measured clockwise from North. So for the fourth one, even though the angle is 40 degrees, it's not 40 degrees clockwise.
20. Have a go at them first as you know what bearings are and how to get them.
