-x(y+z) if x=4, y=-3, and z=-5

32

Step-by-step explanation:

You plug all the numbers in since you're given them

-4(-3-5)

then solve in the parenthesis (PEMDAS)

-4(-8)

then multiply

32

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
