Answer:

And 
Step-by-step explanation:
For this case we assume that for the first square we have the following dimensions:

And we know that:

And the area for the second square would be:

And we know that the sum of areas is 65 so then we have this:

And replacing we got:


We can divide the last expression by 2 and we got:

And we can factorize the last expression like this:

And we have two solutions for
and we got:

Since the length can't be negative we have this:

And 
Answer:
a) √2
b) √(5a)
c) √3
d) -√2
e) -√(3x)
Step-by-step explanation:
This problem set makes use of the relation ...
... a√b = √(a²b)
a) (1/3)√18 = √(18·(1/3)²) = √(18/9) = √2
b) 5√(a/5) = √(25a/5) = √(5a)
c) 2√(3/4) = √(4·3/4) = √3
d) -10√0.02 = -√(100·0.02) = -√2
e) -(1/2)√(12x) = -√(12x/4) = -√(3x)
