Answer:
3 multiply by 6 multiply by 5
= 90 cm²
1. Is a difference of 5 each time so it would be 28,33,38
3. Is the same so go up by 5 each time.
4. Goes up by 3, so your next answers would be 17,20,23.
5.im not sure if that was a typo but it looks like everything after 30 goes up 7 so it would be 51,58,65 hope the last one was a typo but the rest should be right
If 1 and 2 becomes multiplayed gave 3 and 3+3=4 (4-2)+(4-1)= 2+3=4 and 4 is n.
Answer:
scale factor is 4 so it will be 8mm
