Research the history of the Great Pyramids of Giza. In your research, be sure to include the pyramids' actual dimensions such as height and base measurements. Choose one of the Great Pyramids of Giza and create a scale drawing using an exact proportion between the pyramid and scale drawing.
Construct a model of the pyramid using your scale drawing as a guide.
Take a picture of your scale model and upload your work for parts 1, 2, and 3 below.

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !

it should be described as a proper fraction.
