Answer: Add 9 to both sides to complete the square
Step-by-step explanation:
The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:
(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.
(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)
Answer:
You scored more than 80 %
Step-by-step explanation:
21/25
We need to change this to a decimal, then to a percent
21/25 *4/4 = 84/100
This is out of 100 so it is 84%
84>80.
You scored more than 80 %
