Please help, I am terrible at math

Answer:
the correct option is D (12 units, 14 units, 10 units)
Step-by-step explanation:
P= 36
2t + 2 + 2t + 4 +2t = 36
combine like terms
6t + 6 = 36
subtract 6 from both sides
6t = 30
30/6 = 5
T = 5 so plug the t in the other equations
2(5) + 2 = 10 + 2 = 12
2(5) + 4 = 10 + 4 = 14
2(5) = 10
To check combine all the numbers above and you would get 36
