let x = first number; y = second number
y = 2x+7
square root of 30 = average (mean) of the two
mean = sum of x+y divided by 2
(2x+7) + x = 3x+7
mean = (3x+7)/2 = sq rt 30
3x+7 = 2 x sq rt 30
3x = 2 x sqrt(30) -7
x = (2sqrt30 -7) /3 = 1.32
y = 2x+7 = 9.64

Can a square number be a prime number why or why not?
No, square numbers (other than 1) have more than two factors.
What is geometric mean of 0.5 and 9?
The geometric mean of two numbers is the square root of their product. (0.5)(9) = 4.5 Square root of 4.5 = 2.12... That's the answer. In other words, 2.12 is bigger than 0.5 by the same factor that 9 is bigger than 2.12.
