The like terms are 12 and 5, so you have to subtract 5 from both sides.
12 < x + 5
-5. -5
7 < x
We can just switch it around so x is in the left side.
x > 7
Answer:
D is the largest angle

The angle opposite the largest side is the largest and the angle opposite the smallest side is the smallest.
Since 12 is the largest side, angle D is the largest
8 is the smallest side, F is the smallest angle
Answer:
21,800
Step-by-step explanation:
Because 475 x 8 equals 3800 you add 3800 to 18,000 and get 21,800
The derivative is -6sin(3x)
Answer:
x=1
Step-by-step explanation:
This stuff is quite easy in reality. Here's a little example including your numbers.

by this point we are left with simplifying it. Since it's a double negative we get a positive. Thus x=1
