I'll do a few but don't take my word for it ;)
Would you try to answer mine if you can?
1)w^2+x^2... Ect
I would do all these but I have to leave so I'll give you this method:
F.O.I.L
First•first
outer•outer
inner•Inner
Last•Last
Just use this method for the ones in parentheses like 1,2,10,11,12
For the rest I'm still not very good at them myself but try to punch it into a online graphing calculator. Sorry if this doesn't help :(
