Subtract and simplify (2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y) need fast

-2(10.1m+5.9)

Step-by-step explanation:

*First step is to open the brackets which leads to,

2y+14.6m+3.8-34.8m-15.6-3y

*What I did above was to open the brackets of the second equation using the substraction sign

*Second step is to bring like terms together for evaluation which is ,

2y-2y+14.6m-34.8m+3.8-15.6

*Evaluating the above equation

0-20.2m-11.8

The resulting answer is; -20.2m-11.8

The best simplified answer is;

-(20.2m+11.8) ; -2(10.1m+5.9)

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
