8 is the median of the following numbers you have placed down
Note that -5 = x, plug in -5 for x
g(x) = x + 3
g(-5) = (-5) + 3
Simplify
g(-5) = -5 + 3
g(-5) = -2
g(-5) = -2 is your answer

Answer:
56 cm^2
Step-by-step explanation:
Surface area is just finding the areas of each face in a figure. As we are given a net of a figure, it is much easier for us to calculate it.
Area of square base (side^2)
4^2 = 16 cm^2
Area of ONE triangular face (1/2 x b x h):
1/2 x 4 x 5 = 10 cm^2
Multiply that by 4 because we have 4 triangular faces: 10 cm^2 x 4 = 40 cm^2
ADD all the areas of triangles and square:
16 cm^2 + 40 cm^2 = 56 cm^2
HOPE THIS HELPS
Have a nice day!
