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:
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute.
Answer: C
Step-by-step explanation: Since we know both the slope and the y-intercept we can plug them into Slope-Intercept form. Slope-Intercept form is y=mx+b
Since m = 2 and b = -3/4 all we have to do is replace both m and b in the form and that would be the answer. y = 2x-3/4
Answer:
The distance would be about 32 (31.62) feet.
