y = 3(x + 4)^2 + 31
Step-by-step explanation:
We can convert the given quadratic equation into its vertex form by completing the square:
y = 3x^2 + 24x + 43
= 3(x^2 + 8x) + 43
= 3(x^2 + 8x + 4) + 31
= 3(x + 4)^2 + 31
This is the vertex form of the given quadratic equation with (-4, 31) as its vertex

Answer:
0.66 = 66%
Step-by-step explanation:
If we know that a odd-numbered disk is selected, we know that the number is 1, 3 or 5.
So, if it is a red disk, is can be number 1 or 3, so we have two possibilities.
If it is a yellow disk, it needs to be number 5, so we have just one possibility.
We have a total of 3 possibilities, and 2 of them are with red disks, so the probability is 2/3 = 0.66 = 66%
