The ordered pair is only a solution to the first equation, so it is not a solution to the system.

2 x 10 = 20    5 x 5 = 25    20 - 25 = -5     True!

10 + 2 x 5 = 11?    False!    10 + 2 x 5 = 20

So, A and C are the correct answers!

The Great Pyramid of Giza is an example of a square pyramid and is the last
Verdich [7]

Answer:

The surface area of the pyramid is 466,137 squared cubits

Step-by-step explanation:

This is simply asking us to find the surface area of the square based pyramid with the given dimensions.

The first thing we need to know is the principle for finding the surface area of such pyramidal shapes. To get the surface area of a pyramid, we will have to add the base area to the area of the side faces ( lateral area)

The base area of the square based pyramid, will be the same as the area of a square which is = 453 cubits X 453 cubits =205209 cubits^{2}

The lateral area has already been given to us as 260,928 squared cubits.

The surface area of the pyramid is 260,928 + 205209 = 466137 squared cubits

Hence, the surface area of the pyramid is 466137 squared cubits
