The geometric mean of two numbers is the square root of their product:

So, if the product is 8, the geometric mean is 
24? I think if it means he will be thirteen years off his mothers age
Answer:
I need to see the graphs
Step-by-step explanation:
Step-by-step explanation:
I assume
SR = 2x + 23
RQ = x + 21
if that is true, then the situation is completely simple :
14 = (2x + 23) + (x + 21) = 3x + 44
3x = -30
x = -10
SR = 2×-10 + 23 = -20 + 23 = 3
RQ = -10 + 21 = 11
