158 is the answer to your question
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 is D.
As we can observe, in column y
3,4,6,10,18
4-3 = 1
6-4 = 2
10-6 = 4
18-10 = 8
If the sum of the first and last is 64, their average is 32. They will have a difference of 6, so the first number is 29 and the last is 35. The numbers are therefore 29, 31, 33, 35.
260 I believe. Start from the end...
170-80=90
90*2=180
180-50=130
130*2=260
