What's the perimeter for this

There are 8 small sides that measure 3 units each; so that'd be a total of 24 units
There are 2 sides that measure 4x; so they'd equal a total of 8x
& Finally there're 2 long sides that measure (2x-1) each; equal a total of (4x-2)

Add all these up:
(24) + (8x) + (4x-2)

Your answer is:
12x-22

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
