Answer:
brainiest give promise
Step-by-step explanation:
27.9 pounds
24.37 + 3.53 = 27.9
-2(4x-1)=5+7
(4x-1)=12/-2
4x=-6+1
x=-5/4
Given:
The sum of two terms of GP is 6 and that of first four terms is 
To find:
The sum of first six terms.
Solution:
We have,


Sum of first n terms of a GP is
...(i)
Putting n=2, we get


...(ii)
Putting n=4, we get



(Using (ii))
Divide both sides by 6.
Taking square root on both sides, we get

Case 1: If r is positive, then using (ii) we get
The sum of first 6 terms is




Case 2: If r is negative, then using (ii) we get
The sum of first 6 terms is




Therefore, the sum of the first six terms is 7.875.
Answer:
-21/22
Step-by-step explanation:
1.Apply fraction cross multiply
2. Simplify
3.Expand
4.Subtract 24 from both sides
5.simplify
6. Subtract 18x form both sides
7.Simpiify, then divide both sides by -22to get answer.
