I'll treat these like they're two seperate problems because how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)
First one: 3x+9+8x + 12
Collect like terms and simplify
(3x+8x)+(9+12)
11x+21
Second one: 2x + 6+x² + 6x + 9
Collect like terms and simplify
8x+15+
Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!

(4x-4y) + (-9x-4y) = -2 + -3
gather like terms :
4x-9x-4y-4y = -5
-5x-8y = -5
I think the answer would be -2 because they are taking 2 away from the equation. hope it helps.
It depends on what you get if are ranked low you will need help with the skill and if rank average you just are in normal classes and if you are ranked above average you probably are either left in the average class or go to advance math.
Its the first one 6(7+12) i took the test and got the answer wrong but then i found out it was this so i hope i helped you ;-;
