Step-by-step explanation:
The given series is a geometric series because the consecutive terms differ by a common ratio. The formula for determining the sum of the first n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
a = 3
r = 6/3 = 12/6 = 2
n = 15
Therefore, the sum of the first 15 terms, S15 is
S15 = (3 × 2^(15) - 1)/2 - 1
S15 = (3 × 32767)/1
S15 = 98301
X=14
Y=14
Perimeter=56
The reason is because if you see 8 and 6 you can see that the lines are equivalent so I just assumed that the missing lines are 8 and 6. So I added the number up causing x and y to be 14 then for perimeter I simply just multiplied 14x4 which is 56.
25a + 5b - 13
5(5a + b) - 13 is your answer
using the distributive property, we can distribute 5 to all terms within the parenthesis:
5(5a + b) - 13 = 25a + 5b - 13
5(5a) = 25a
5(b) = 5b
25a + 5b - 13 = 25a + 5b - 13 (True)
hope this helps
