Answer:
S8 = 112
Step-by-step explanation:.
The question is incomplete
Assuming we are given the following
First term a =7
number of terms n = 8.
Common difference d=2
We can find the sum of the first 8terms S8
Substitute the given values
S8 = 8/2[2(7)+(8-1)(2)]
S8 =4(14+7(2))
S8=4(14+14)
S8 = 4(28)
S8 = 112
Hence the sum of the first 8terms is 112
Note that the values are assumed values
3) HK = 2√5
midpoint of HK = (8,8)
4) SR = 2√2
R = (6,2)
5) Instead of walking a total of 14 he only would have walked a total of 10.
Hope this helps! ;)
