Example 2: SIMPLIFY 12 + (18 - [6 + 2]) STEP 1: Add 6 + 2 because these numbers are
inside the inner grouping symbols. [ ]
12 + (18-8)
STEP 2:
12 +

Type the correct answer,
then press Enter.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

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

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
