2(a+b)+ 4m(a+b) factor out the greatest common factor​

Step-by-step explanation:

Find the Greatest Common Factor (GCF).

Factor out the GCF.

now, Simplify each term in parentheses.

hence, if we factor out the GCF (greatest common factor), we get the answer 2 (a + b) (1 + 2m).

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
