Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.

I applied the distribution technique to the original question.
0.578=289/500, 3.5= 3 1/2, 2.73= 2 73/100, 0.4211= 4211/10000. Hope this helps :)
Answer:
x = 100
Step-by-step explanation:
The area of the left square is 3600
A =s^2
3600 = s^2
Taking the square root of each side
60 =s
The area of the right square is 1600
A =s^2
1600 = s^2
Taking the square root of each side
40 =s
Adding the lengths
60+40 =x
100 =x
