Answer:
F. 6π is the correct answer
As the diameter of the 2nd circle is 2x+3, its radius will be (2x+3)/2 which is equal to x + 1.5
But as it is identical to the 1st circle their radii will be equal.
Therefore, 2x = x + 1.5
Therefore, 2x - x = 1.5
Thus we get that x = 1.5
Therefore, r (radius) = 2x = 2*1.5 = 3
Now we can find the circumfrence by the equation circumference = 2πr
Therefore, circumference = 2*π*3 = 6π
To complete the square of a polynomial, use the term "(b / 2) ^ 2".
In this polynomial, the "b" term is 14.
Plug that in.
(14 / 2) ^ 2
7 ^ 2
49.
The answer is C.
Answer:
A
Step-by-step explanation:
Since both qualities in the original statement are "positive", they would also be true if they are both "negative"
Answer:
- 22
Step-by-step explanation:
let the number be n then 2(n + 9) is the sum of the number and nine doubled, thus
2(n + 9) = n - 4 ← 4 less than the number
Distribute parenthesis
2n + 18 = n - 4 ( subtract n from both sides )
n + 18 = - 4 ( subtract 18 from both sides )
n = - 22
The number is - 22
