Answer:

step 1: move the -4 to the right: x^2 -2x = 4

step 2: add 1 to each side: x^2 -2x + 1 = 4 + 1

step 3: factor the left side and simplify the right side: (x-1)^2 = 5

step 4: take the square root of each side: x - 1 = sqr root of 5

step 5: move the 1 to the other side: x=\sqrt{5} + 1 and x = \sqrt{5} -1

1. The great pyramid at Giza is the largest pyramid in the world, the area of its square base is 52,441 m squared, what is the l
AlladinOne [14]

Answer:

The length of each side of the base is 229\ m

Step-by-step explanation:

we know that

The area of a square is equal to

A=b^{2}

where

b is the length side of a square

In this problem we have

A=52,441\ m^{2}

so

substitute in the formula

52,441=b^{2}

Square root both sides

b=\sqrt{52,441}\ m

b=229\ m
