a landscaper uses square tiles to make garden paths the ends of the paths are always 2 tiles wide, and the center portions of the paths are 3 tiles wide. what equation gives the total number y of tiles needed to make a path with a length of x tiles. the landscaper has 100 tiles. what is the length of the longest path that the landscaper can make

x = total length
x2 = center part
2 = end parts
y = 2*2 + 3(x2)
y = 4 + 3x  6
y = 3x  2
If you have 100 tiles,
100 = 3x2
102 = 3x
x = 34
So, a path of length 34 uses 4+96 = 100 tiles
