R = 14
s = 11
2(14)+2(11)=50
28+22=50
2(14) - 11 =17
28 - 11 =17
Answer: Most likely 13cm
Step-by-step explanation: <em>because it’s between 10cm and 16cm and thes no picture and set of choices so I hope this right.</em>
2x-13+3x-8+2x-3+2x-7+3x-1+2x+11+2x+9= (7-2)×180
16x-12=(7-2)×180
(7-2)×180 Work this out on a calculator
And then that answer=16x-12
Then you solve by adding 12 both sides and dividing by 16 both sides to get what x is.

Step-by-step explanation:
Given the function 
The average rate of change of the function h(x) over the interval
can be calculated using formula

In your case,

so the average rate of change is
