Answer:
B
Step-by-step explanation:
We can get two equations from the inequality:

We just need to simplify both equations to get our answers:


The two answers we get are:

Which is also B.
Equation symbol is the name of what you are asking for
1. P = 2(9) + 2(4.5)
P = 18 + 9
P = 27 m
2. P = 5.2(2) + 1.3(2)
P = 10.4 + 2.6
P = 13 ft
3. P = 12.9(2) + 4.7(2)
P = 25.8 + 9.4
P = 35.2 cm
