Answer:
Step-by-step explanation:
Given

Determine the average rate of change over [2,7]
This is calculated as:
In this case:
and
So, we have:
From the table:
f(7) = 1.91
f(2) = 1.26
I'm not sure if that's what you mean, but the difference between 6010 and 5060 is 950, so to find a number in a halfway between them I divided 950 by 2 (which is 475) and added it to 5060 (or substracted from 6010 - it's the same). Next I added the same number (475) to 6010. So finally it would like like this:
6,485 ; 6,010 ; 5,535 ; 5,060
1/3
I was taught to divide each side by the same number
8/8= 1
24/8=3
=1/3
If width is w the length can be represented as 5/2+2w.
Formula for perimeter is 2l + 2w
So it would be 2w + 2(5/2 + 2w)
OR 2w + 5 + 4w
OR 6w + 5
See if this helps ;)
