Answer:

Step-by-step explanation:

The domain of a graph is all of the x-values of the graph. Since the graph looks like it continues and never ends, every single x value is included in the domain, thereby making all reals the correct answer
P= 2l + 2w
P= 2(15) + 2(12)
P = 30 + 24
P = 54
You will need 54 ft baseboard
A= LxW
A= 15x12
A= 180
You will need 180 one foot square tiles
