Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer
when using 3.14 for pi
Woops: forgot to add the diameter of 12 so we would have 30.84
<u><em>Answer:</em></u>
The height of the stack =
in
<u><em>Explanation:</em></u>
We are given that Jean stacks a dictionary on top of a novel.
This means that the total height of the stack will be equal to the height of the dictionary added to the height of the novel.
<u>From the givens, we have:</u>
height of dictionary =
in
height of novel =
in
<u>Now, adding the two height, we will have:</u>
Total height of stack = height of novel + height of dictionary
Total height of stack =
in
Hope this helps :)
Answer: B.f(n)9n-12
Step-by-step explanation:
Answer: The correct option is (c) 
Step-by-step explanation: We are given to solve the following quadratic equation by the method of completing the square:

Also, we are to find the constant added on both sides to form the perfect square trinomial.
We have from equation (i) that

So,

Thus, the required solution is
and the value of the constant added is 
Option (c) is correct.
