Find the surface area of a square pyramid with base edges of 8 feet. The height of each lateral face is 9 feet. Explain or show how you got your answer.

The answer is 208.

base edge x base edge = 8 x 8 = 64

bse edge x lateral face = 8 x 9 = 72

72 x 2 = 144

144 + 64 208

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
