Ans.5) you can re-write 3 3/10 as 33/10
Now, you have to find two numbers whose sum would be 33/10.
Try to fix the denominator, and change numerator...like
it would be 13/10 + 20/10 or 15/10 + 18/10.Ok..
You can do your 6th ques. in same manner.
Did you understand?Or not??
The answer is x²-8x+13=0
Here is how:
[x-(4+√3)][x-(4-√3)]=0
expand and simplify:
x² -(4-√3)x - (4+√3) +(4+√3)(4-√3)=0
x²-8x+13=0
possible solutions for equation 
is

Answer:
x²+(1/x²) = 47
Step-by-step explanation:
by identity : (a+b)² = a²+b²+2ab
(x+1/x)²= x²+(1/x)²+2(x)(1/x)
(x+1/x)²= x²+(1/x²)+2....(1)
since : (x²+1)/x = 7
(x²/x) +(1/x) = 7
x + (1/x )= 7
put the value for : x +(1/x) in (1) :
49 = x²+(1/x²)+2
x²+(1/x²) = 47
