Which expression is equivalent to 8x – 2y + x + 2? A) 4x
B) 83
(c) 6x – 2y
D 10x - 2y

D

Step-by-step explanation:

To find this out, we have to simplify the expression 8x-2y+x+2, so using PEMDAS, we can figure out that the first step here would be addition.

Combining like terms, we add (8x+x), which leaves the expression like this: 9x-2y+2.

So in conclusion, I have no idea what this would be since you can't simplify any more. My guess would be D, because that's closest, but you can't get rid of the 2, or the x or y terms without more information.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
