I believe it should be B.156 square feet because in order to find the area of a square, you gotta multiply 13ft and 12ft. Once that is solved your answer should be 156.
Answer:
-105
Step-by-step explanation:
Substituting is like "plug and chug", so we can plug in -2 into the expression and get 
, which simplifies into 21*-5, or -105. 
Bill's age = x
Eya's age = 3x - 5
Eya is 28
28 = 3x - 5
28 (+5) = 3x -5 (+5)
33 = 3x
33/3 = 3x/3
x = 11
Bill = x
x = 11
Bill is 11 years old
hope this helps
