12/30 = 18/45, so first you're going to cross multiply and you'll get (30)(18) = (12)(45). Then you can see that 540 = 540 same number so they're proportional...
BTW THIS WAY IS A LOT EASIER.
12/30 = 2/5
18/45 = 2/5
So yes, in summary, they're proportional to each other. Hope this helps, have a BLESSED and wonderful day! :-)
9. Wrong name for this angle: <2
10. Wrong name for this angle: <3
Well the first problem that i solve is you have to move 12 it will give you
-3y power 12 - 3y + 12
