Sorry if you can't see it correctly !! the question is- Determine the value of the expression below when d = 9.

–28

Step-by-step explanation:

9 + 3(10 ÷ 2) – 52

Solve parentheses first: 9 + 3(5) – 52

Order of Operations says to solve multiplication next: 9 + 15 – 52  

Simplify the addition: 24 – 52

Subtract 52 – 24 and negate the –28

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
