Answer:
(x + 9)² = 36
Step-by-step explanation:
Given
x² + 18x + 57 = 12 ( subtract 57 from both sides )
x² + 18x = - 45
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(9)x + 81 = - 45 + 81
(x + 9)² = 36
$320 5 times 20 is 100 so you have to times 16 by 20 to get the total 100% of the video game system
I believe your answer would be B, Bisect AB, but not be perpendicular to it.
