If the fractions you're adding have different denominators, you can't do
anything with them until they have the same denominator.
The least common multiple of the original denominators is usually the
best choice for a common denominator to change them to.

Answer:
Step-by-step explanation:
Remark
A right triangle with one other angle = 45 degrees is isosceles (two sides are equal). So the bottom line of the square is also s
Formula
s^2 + s^2 = 20^2 Add the terms on the left. Square the right.
Solution
2s^2 = 400 Divide by 2
2s^2/2 = 400/2 Simplify
s^2 = 200 Take the square root of both sides.
Answer
sqrt(s^2) = sqrt(200)
s = 14.1 or s = 10*sqrt(2)
