10x=1/2x+3
I think it's right, but not 100% sure
Use a calculator. The sine of 78 degrees is .98.
3/4 is as simple as it gets 5/10- 1/2
I believe the correct answer should be the second option. This makes the most sense given the coordinates.

The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2
