Write the product as a sum: 1. 4sin(22r)cos(16r)=
2. sin(13.2x) + sin(8.2x)=
3. 8cos(30z)cos(2z)=
4. 6sin(36q)sin(23q)=
5.sin(19.8w)-sin(2.4w)=
6. cos(3.6q)+cos(2.6q)=
7. cos(22.2r)-cos(8.2r)=

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
