Given that a ≠ b, is it ever possible to have
Sqrt a+ sqrt b = Sqrt a+b? Explain.

It’s hard to understand what you put.. can you show a picture ?

It should be a or d i’m not sure

22. so easy i think that’s it tell me i’m right

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
