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!

Answer:
Step-by-step explanation:
ill try this one in a few minutes for you.
First we need to find the total amount of servings needed.

Answer:
x=$59.69
Step-by-step explanation:
We can create a proportion to find the answer.
Thus, we get 4 hr/$39.79=6 hr/$x.
Cross multiplying gives us 4x=238.74, and solving for x gives us $59.685.
We can round to $59.69.
