The final answer would be:
r+2
Exact steps are shown in the attached picture.
That could possibly be 6-7ft
Your answer would be D. Bc you haven't divide a from b to get f on the other side if the equation.
271, since if the last 4 numbers didn't change, you can only change the first 3, so that would be 270 different numbers, not forgetting just 2014 so it makes it 271
I won’t be doing all 4 of them (so that you can learn how to do it yourself successfully, without
me just giving you all the answers) but I did 11 which hopefully helps you understand?
Sorry if my handwriting’s a bit on the messy side :))
