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
32/36 can be simplified twice into 16/18, and then into 8/9.
Answer:
A.
Step-by-step explanation:
In the figure attached, the oblique prism is shown.
The volume of the prism is:
V = b*h
where h is the height and b is the area of the base
Given that the base is an isosceles right triangle, its area is:
b = 1/2*x²
The height of the prism is (x + 2). Then, the volume is:
V = 1/2*x²*(x + 2)
V = 1/2*x³ + x²
Answer:5

Answer:
105,660 times
Step-by-step explanation:
7 times 65=445 times 60=26 700
2 times 118=236 times60=14 160
15 times 72=1080 times 60=64 800
26700 plus 14 160 plus 64 800=105,660
