Answer:
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
Add 8.2 to both sides of the inequality. Then, you obtain:
Now you must divide both sides by -1.2, as you can see below:
(The direction of the sign will change).
Therefore, you obtain the following solution:

Step-by-step explanation:
Use the form for the factoring of the sum of cubes.
To make this easier to write, we'll use the substitutions ...
a = sin(θ), b = cos(θ)
It looks like you may want to simplify ...
(a³ +b³)/(a +b) +ab
= ((a +b)(a² -ab +b²))/(a +b) +ab
The factors of (a+b) cancel. In this case, we know that a² +b² = 1, so this becomes ...
= (1 -ab) +ab
= 1
