Mathematics Homework Help

I’ll upload the pictures of the questions one at a time because some questions have multiple parts to them.

2 has parts (a-c), 3 has parts (a-i), 4 has parts (a-g), 8 has parts (a-b), 11 has parts (a-g), 13 has parts (a-f), 14 has parts (a-f), 18 has parts (a-d), and 20 has parts (a-d).
