Surface area is:
6*8=48
12*10=120
8*12=96
6*12=72
48+72+120+96 = 336
The surface area is 336 square km
The answer is 0. BTW THAT IS EASY
Answer:

Step-by-step explanation:
Simplify the following:
⇒-9 x + 12 x + 10
Grouping like terms:
⇒(12 x - 9 x) + 10
12 x - 9 x = 3 x:
⇒3 x + 10
Answer:
See below in bold.
Step-by-step explanation:
The domain is the list of x values and the range is the list of y values.
Reading from the graph: The domain is {-3.5, -2, 0, 3.5}.
The range is {3, 1.5, -0.5, }.
