I need help with finding out if it’s a perfect square trinomial

Yes,

Step-by-step explanation:

since it has the format of a² + 2ab + b². The format is expressed clearly in 64s² - 112s + 49, where 64 and 49 are perfect squares, and 112 is double the product of 8 and 7 which are the square roots of 64 and 49, respectively.

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
