Okay I will help you as much as I can lol. So the 5th is 8x10 on th 6th per 4x10 on the 4th (I’m not english so I don’t know how to write these in english, but hopefully you will understand me) So you can solve thi with writing these under each other. And with multiplication, you can simplify. So you divide 8 with 4 so you get 2. The you divide 10 on 6 with 10 on 4 and you just simply 6-4 and you get 2. and 10 on the 2nd is 100. then you multiply them with each othe. 2X100 is 200. so the answer for 5th is 200

the 8th is: (x+4)(x-3)
Okay I can’t make more repliesXDD Tell me if you need more help, or if I’m being helpful at all
but here is the solution for 9th: 2x((x+6)+(x-4)) so: 4x+4

yeah sure the answer is 400
the method:
X multiplyed by 0.85=340
so you just 340/0.85=400
I like to do these kind of exercises. My math exercises just not that exciting. (I’m in function drawing right now )

Uh, what do you mean? The way you phrased it makes it seem like £360 is the original price
Do you mind clarifying it a little more? I love helping out with math stuff

Edit: If you meant that £360 was the price after the tax was added, then your answer should be £300 for the original price. Let me know if you want me to explain how I got that, okay?
