Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one. Please have a look at the attached photo.
My answer:
- The length of the large rectangle is: 5
- The width of the large rectangle is: 7
=> Area of the large rectangle = length × width = 7*5 = 35 square units
- The length of the middle rectangle is: 7
- The width of the middle rectangle is: 4
=> Area of the middle rectangle = length × width = 7*4 = 28 square units
- The length of the small rectangle is: 7
- The width of the small rectangle is: 3
=> Area of the small rectangle = length × width = 7*3 = 21 square units
Area of top and the bottom triangles =2*
Total surface area = 35 + 28 + 21 + 12 = 96 square units
Option C: -3 is the average rate of change between and
Explanation:
The formula to determine the average rate of change is given by
Average rate of change =
We need to find the average rate of change between and
Thus, from the table, we have,
,
,
Thus, substituting these values in the formula, we get,
Average rate of change =
Thus, the average rate of change between and
is -3.
Hence, Option C is the correct answer.
