Answer:
x = 4 ± 
Step-by-step explanation:
Given
(x - 12)(x + 4) = 9 ← expand the left side using FOIL
x² - 8x - 48 = 9 ( ad 48 to both sides )
x² - 8x = 57
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 57 + 16
(x - 4)² = 73 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±
100000+200000=300000
28x=300000
X=10714

Answer:
6
Step-by-step explanation:
11 1/2 = 11.5
2 1/4 = 2.25
11.5 ÷ 2.25= 5.11
she needs 6 containers because you round up 5.11 to 6.
if your doing the work in fractions rather decimals let me know and I can explain it that way too
I believe the correct answer from the choices listed above is option A. THe correct classification of the polygon in the figure would be a concave hexagon. Counting the number of sides, we have 6 sides making it a hexagon. It is concave since one side is <span>hollowed inward.</span>
