Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

here [ a, b [ = [ 3, 5 ]
From the table
f(b) = f(5) = - 26
f(a) = f(3) = - 10
Hence average rate of change
=
=
= - 8 → A
First, we must subtract
57
-
26
______
31
Second, we isolate the variable!
X + 0 = 31 - 5
X+0 = 26
X=26
Finally,Plug it in
26 + 5 = 57 - 26
26 + 5 = 31
31 = 31

Good Luck!
Well Briana would have finished at 10.63 seconds (meaning she would have won XD)
Three-tenths can also be expressed as 0.3, and 0.3 + 12.08 is 12.38.

Answer:
For grid, Please see attachment area of rectangle.
Explanation:
We are given the area of rectangle is 1,125 square unit whose one side is 25 units.
As we know the formula of area of rectangle 
Let 25 units is width of rectangle
Area = 1,125
units
Dimension of rectangle 45 x 25.
Now we draw the grid graph of rectangle.
First we take a grid paper with 1 square unit area of each box. Now we draw line with 45 unit horizontal(Length) and 25 unit vertical (Width).
We make a closed figure with four line opposite side equal and parallel.
Inside box, total number of box must be 1,125 because area of 1 small box 1 square unit.
Total area of all box = 1,125 x 1 = 1,125 square units.
