To find k
You can do
C-a((b/2)^2))
This is because when you complete the square you have the c value that you have initially minus the new c value which is found by (b/2)^2 and if you factored a number out then multiply it to that.
So in this case
31- 1(10/2)^2
31-(5)^2
31-25
6
The answer is 2.84375 because multiplying
Answer:
44 mph
Step-by-step explanation:
0.25 hour * 4 = 1
11 * 4 = 44
44 mph
Step-by-step explanation:
10x² + 11x − 6 = 0
10x² + 15x – 4x – 6 = 0
5x(2x + 3) – 2(2x + 3) = 0
(2x + 3) (5x – 2)
