If the letter z's are distinctly different, there are P(5,5) arrangements. That is
If the z's are interchangeable, the number of different arrangements is given by
Answer:
Suppose 3 consecutive integers are X-1,X,X+1
Step-by-step explanation:
Sum = X-1+X+X+1= -78
3X=-78
X= -78/3
X= -26
3 consecutive integers are, -27, -26,-25.
smallest integer is -27

Answer:
The range is [-1, ∞).
Step-by-step explanation:
The points where the graph of this function cut the x axis are at x = 2 and x = 4 , it opens upwards and has a minimum value.
It has a minimum value when x = (2 + 4) / 2 = 3.
When x = 3, f(x) = (3 - 4)(3 - 2) = -1.
So the range is all real values of x >= -1, or [-1, ∞)

Answer:
Step-by-step explanation:
If the square starts as n rows of n columns, adding another row of n columns will make a rectangle with dimensions n+1 rows by n columns.
__
The total number of tiles in the rectangle is said to be ...
n(n+1) = 2256
n^2 +n +1/4 = 2256 1/4 . . . complete the square
(n +1/2)^2 = (47 1/2)^2 . . . . rewrite as squares
n = 47
