Please help me solve for x

x = 4

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, thus

7x - 4 = 24 ( add 4 to both sides )

7x = 28 ( divide both sides by 7 )

x = 4

two data sets with the same median will not have the same varaibility

step-by-step explanation:

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
