Last one:
i know how to start it but then idk
Graphical solution : https://www.desmos.com/calculator/jxu8ptf7ql
Result = 24
Proof Let a ≈ 20 Let a = 21
abs( ≈20- 20) = 0 abs ( 21 - 20 ) = 1
abs(6 - 0) = 6 abs (6 - 1) = 5
abs ( 2 - ≈20 - 6) = abs ( ≈ -24) ≈ 24 abs ( 2 - 21- 5) = abs ( -24) = 24
oh, thats how u do it! thanks!
If 20 < a <= 20 what is the value of |2-a-|6-|a-20|||
Isolate the absolute value and Write two equations without absolute value bars
0 < |a-20| <= 0
a – 20 > 0 or a – 20 <= 0
