* Lets explain how to solve the problem
- The rule of expand the binomial is:
∵ The binomial is
∴ a = 10k , b = -m and n = 5
∴
∵ 5C1 = 5
∵ 5C2 = 10
∵ 5C3 = 10
∵ 5C4 = 5
∵ 5C5 = 1
∴
∴

Answer:
2 x
Step-by-step explanation:
The diagonal divides the square into 2 right angles with legs s and hypotenuse x
Using Pythagoras' identity on one of the right triangles, then
s² + s² = x²
2s² = x² ( divide both sides by 2 )
s² = ( take the square root of both sides )
s = =
Thus
perimeter = 4s = 4 × =
Multiply numerator/ denominator by
perimeter = = 2
x
For this case, we must build a quotient that, when multiplied by the divisor, eliminates the terms of the dividend until it reaches the rest.
The attached figure shows the quotient given by:
