Determine the perimeter of a rectangle with a length of 2 feet and a width of 6 inches. (Multiple choice) —————
2.5 feet
8 feet
5 feet
16 feet

D or 16

Step-by-step explanation:

For perimeter, the formula is 2(L + W) where L is length, and W is width.

So 2 ( 2 + 6 )

= (4 + 12)

= 16

think about it deeply and passionately about this property

i am sorry

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
