Answer:
b = 2
Step-by-step explanation by completing the square:
Solve for b over the real numbers:
b^2 - 4 b + 4 = 0
Write the left hand side as a square:
(b - 2)^2 = 0
Take the square root of both sides:
b - 2 = 0
Add 2 to both sides:
Answer: b = 2
The total number of games that they played is 30.
(18 divided by 30 equals 0.6) (60%)

(30 subtract 18 equals 12)
The symbol that would accurately feel this blank is ">" because when x=6, the equation on the left is equal to 48. An easy way to remember which sign to use is that the arrow points to the smaller number. Since the equation on the left equals 48, we know that 28 is the smaller number. Therefore, the arrow points to 28.
