What is Fermi Paradox?
The Fermi paradox is a disagreement between different high estimations for the existence of alien life and the lack of conclusive, blatant proof for it. If life were so simple, "someone from someplace must have come knocking by now," as one story from 2015 put it. Due to a casual conversation he had with fellow physicists Edward Teller, Herbert York, and Emil Konopinski in the summer of 1950, Italian-American Enrico Fermi is known for the paradox. The men talked about recent UFO sightings and the potential for faster-than-light travel as they were walking to lunch. Before Fermi abruptly asked, "But where is everybody?" during lunch, the conversation shifted to other topics (although the exact quote is uncertain).

Answer:
there are no extraneous solutions to the equation
Step-by-step explanation:
Given
= x + 2 ( square both sides )
8x + 9 = (x + 2)² ← expand
8x + 9 = x² + 4x + 4 ( subtract 8x + 9 from both sides )
0 = x² - 4x - 5 ← in standard form
0 = (x - 5)(x + 1) ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 1 = 0 ⇒ x = - 1
As a check
Substitute these values into the equation and if both sides are equal then they are the solutions.
x = 5 : 
= 
= 7
right side = 5 + 2 = 7
left side = right side ⇒ x = 5 is a solution
x = - 1 : 
= 
= 1
right side = - 1 + 2 = 1
left side = right side ⇒ x = - 1 is a solution
There are no extraneous solutions
Answer:
Step-by-step explanation:
126 + 44 = 170 ( total for under 25s)
186 - 56 = 130 (online for 25s - 50s)
154 - 58 = 96 ( in stores for aboves 50s)
314 for ONLINE TOTAL
196 for IN STORES TOTAL
510 for TOTAL TOTAL
A = 170
B = 56
C = 96
D = 96 - 58 = 38
E = 314 - 196 = 118
F = 510
