Plz.. Shawn has $14 and earns $12 for each lawn he mows. If he
mows 4 lawns and buys 5 DVD's that each cost $11.95 each,
including tax, how much money does he have left?

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

combine all like terms then its just a 2 step equation
