Answer:
B
Step-by-step explanation:
x² - 12x + 11 = 0 ( subtract 11 from both sides )
x² - 12x = - 11
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 11 + 36
(x - 6)² = 25 ( take square root of both sides )
x - 6 = ± 
= ± 5 ( add 6 to both sides )
x = 6 ± 5
Then
x = 6 - 5 = 1 ⇒ (1, 0 )
x = 6 + 5 = 11 ⇒ (11, 0 )
Since im lazy im not going to do the work. an inch = 2.57 centimeters. so you have 1 inch - 2 centimeters yes? multiply it by two, and then multiply the inches. The answer would be <span>2 cm × 3 cm. Hope I helped.</span>
If there must be LESS than 12 people in the tour group, then it would automatically take out the n>12 because n>12 represents n being MORE than 12, so your answer would be n<12. I hope you aren't totally confused, and good luck on the test!!! I am working on my math skills and I just did this quiz, so the answer is in fact, <. Make me brainliest please, would truly help.
Step-by-step explanation:
the perimeter = 2 ×15 + (π×d)
= 30 + (3.14 ×10)
= 30 + 31.4
= 61.4
The length of the fencing corresponds to the length of the perimeter of the garden:
We also know that the perimeter of a circle is given by:
where r is the radius of the circle.
Putting together the two equations, we have
from which we can find r, the radius of the garden:
