x3
x + 3 + x
Answer:
x + 3 + x
Step-by-step explanation:
The sum of three terms means that three terms have been added.
3x is the answer; it does not show the terms being added.
3+x is the sum of two terms.
x³ is a product.
x+3+x shows 3 things being added, so it is the correct answer.

sin240° - 210° → sin30° >> ½

** I do not have Unit Circle video uploaded yet, but if I need to, just notify me in the comments or on of course, You-Tube.
*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.
**** Now, 60° is the main possible answer, however, it falls in between 0° and 90°, not 180° and 270°.
