The perimeter of a rectangle is 68 km. If the length is 2 km less than three times the width, w what is the length of the rectangle

Step-by-step explanation:

68=6x-4+2x

68=(6+2)x-4

68=8x-4

68+4=8x-4+4

72=8x

72%2F8=8x%2F8

9=cross%288%29x%2Fcross%288%29

9=x

The width:x=9km

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

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
