Answer:
-5xyz -8x + 62
Step-by-step explanation:
First add up all the 3 sides.
3x²y + 12x²y + 15x²y = 30x²y
4xyz + 7xyz + 3xyz = 14xyz
-12 + 50 = 38
-7x = -7
All added up is 30x²y + 14xyz + 38 - 7x
The perimeter was 30x²y + 9xyz - 15x + 100
We find out take away the added sides from the perimeter
30x²y - 30x²y = 0
9xyz - 14xyz = -5xyz
-15 x - (-7x) = -15x + 7x = -8x
100 -38 = 62
The fourth side and answer would be -5xyz -8x + 62
