The correct answer is the second (-2^4). 1, 3 and 4 give you an answer of 16 and 2 gives you -16
In every case, you're finding the surface area of a rectangular prism. That area is the sum of the areas of the 6 rectangular faces. Since opposite faces have the same area, the formula can be written
... S = 2(LW +WH +HL)
The number of multiplications can be reduced if you rearrange the formula to
... S = 2(LW +H(L +W))
where L, W, and H are the length, width, and height of the prism. (It does not matter which dimension gets what name, as long as you use the same number for the same variable in the formula.)
When you're evaluating this formula over and over for diffferent sets of numbers, it is convenient to let a calculator or spreadsheet program do it for you.
1. S = 2((5 cm)(5 cm) +(5 cm)(5 cm +5 cm)) = 2(25 cm² +(5 cm)(10 cm))
... = 2(25 cm² + 50 cm²) = 150 cm²
2. S = 2(12·6 + 2(12+6)) mm² = 2(72 +36) mm² = 216 mm²
3. S = 2(11·6 + 4(11 +6)) ft² = 2·134 ft² = 264 ft²
4. S = 2(10·4 +3(10 +4)) in² = 164 in²

Answer:
B
Step-by-step explanation:
N=4x0+12=12
Let's assume
independent variable is x
dependent variable is h
A linear function h models a relationship in which the dependent variable increases 1 unit for every 5 units the independent variable decreases.
so, we can use formula of linear function
where
m is slope
now, we can plug values
The value of the function at 0 is 3
so, at x=0 , h=3
we can use it and find b
now, we can plug back
now, we can draw graph
