The pyramid consists of 4 congruent triangular faces, and 1 square base.
Area of 1 triangular face:
1/2 * (5 in)/2 * (5.6 in) = 7 in^2
Area of base:
(5 in)^2 = 25 in^2
Then the total surface area is
4 * (7 in^2) + 25 in^2 = (28 + 25) in^2 = 53 in^2

Answer: 21
k(x) =x^3-2x
k(3) =3^3-2*(3)
k(3) =27-6
k(3) = 21
B
Both of them have the same variable and are both raised to the 5th power (Like the example in the last sentence of the text)
The answer is D
Because
-35/65 = -0.53
I hope that's help:)
