Because the left side is eclipsed in an absolute value, we have two possible values of x, denoted by:
2x+4 = 12 and -(2x+4) = 12
Solving for both of these, we are presented with the two values of x:
x = 4 and x = -8
Answer:
8+2j like you say let j be the variable and more than means+
(12 - 2) * 180 = 1,800/12 = 150
(8 - 2) * 180 = 1,080/8 = 135
B. 8 sides
Using PEMDAS,
27-10=17
17*4=68
64/68=0.94 (rounded to the nearest hundredth)
