The expression on the left side of an equation is shown below. 3(x + 1) + 9 = if the equation has no solution, which expression can be written in the box on the other side of the equation? a. 3(x + 4) b. 2(x + 6) + x c. 4(x – 3) – x d. 3(x + 1) + 9x

C. 4(x – 3) – x

Step-by-step explanation:

When simplified, the expression will have no solutions.

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
