I think the answer is 19.5
they all multiple by 4 like y 2/4+ 4y- 21
17) -3 + x > 19
x > 19 +3
x > 22
18) -3 <_ 6x - 1
(Here, please note that <_ is lesser than or equal to and >_ is greater than or equal to)
6x >_ -2
x >_ -1/3
19, 20, 21) now onward Ima type just the answers -_-
x > -7/2
x < 12
x<_ 2
First you have to find the area of each polygon by adding each number on all the sides then if this helps put the eqaule number of the polygon by it then do the same with the other polygon and if there the same you put eaquvilant or just circle both of them
