Answer:
B
Step-by-step explanation:
Given
x² - 18x + --- = 4 + ----
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 9)x + 81 = 4 + 81
(x - 9)² = 85 ( take the square root of both sides )
x - 9 = ± ( add 9 to both sides )
x = 9 ± ← exact solutions
its is 50 i am sure of it
because 50 is the middle and it is directly on the middle also i have the same school program and i pased that test
Answer: 60% decrease
Look at the attachment

x = 3
4 + 12.5 > 11x - 3.5 - 2x
16.5 = 5.5x
16.5/5.5 = x
