The number added to the polynomial is
Explanation:
The given polynomial is
We need to determine the number that is added to the polynomial to complete the square.
The last term of the polynomial can be determined by dividing the term 21 by 2 and then squaring the term.
Thus, we have,
Last term =
Now, squaring the term, we have,
Last term =
Thus, the number added to the polynomial by completing the square is
Answer:
A
Step-by-step explanation:
Null means nothing, or zero.
In the case of matrix, a null matrix is a matrix where all its elements are zeros.
They can be of any order, 2 x 3 matrix, 2 x 4 matrix, 2 x 2 matrix etc.
A matrix has a diagonal and other values (non-diagonal). When diagonal is 0 only, and not other, its is still not null. When all the values of a matrix are 0, all the elements are 0, then we call that Null Matrix.
It is equivalent to Zero (0) in the number system.
Correct answer choice is A
Area = length*width
Width = area/length
width = (65 1/4 in^2)/(9 2/3 in)
width = 6 3/4 inches
Hope this helps :)
