Answer:
23
Step-by-step explanation:
25 + 17 + 38 + 11 + 24 = 115 / 5 = 23
Answer: Option D

Step-by-step explanation:
For a quadratic function of the form

The x coordinate of the vertice is:

In this case the function is:

So

The x coordinate of the vertice is:

The y coordinate of the vertice is:

The vertice is: (-3, -11)
The form e vertice for a quadratic equation is:

Where
the x coordinate of the vertice is h and the y coordinate of the vertice is k.
Then h=-3 and k =-11
Finally the equation
in vertex form is:

Three consecutive integers are x, x+1, x+2.
The volume of a rectangular box is the product of its three dimensions. The volume is 138000 cm³.

The dimensions of the box are 23 cm x 24 cm x 25 cm.
n(A), n(B) and n(AnB) are given and n(AUB)'s complement is asked.
