In order to find the answer, we have to find common difference for each.
Option 1.
first difference= 3-(-1) =4
second difference = -3-3=-6
here we dont have a fixed common difference, so its not an arithmetic series.
Option 2.
first difference= -2-2=-4
second difference = -6-(-2) = -4
third difference = -10-(-6) =-4
here we have a fixed common difference, so its an arithmetic series.
Option second is the correct answer
Im guessing this is simplify so the answer would be

Answer:
27 logs
Step-by-step explanation:
<u><em>4hrs = 6 logs</em></u>
<u><em></em></u>
<u><em>18hrs= ?x</em></u>
<u><em></em></u>
<u><em>Then you cross multiply.</em></u>
<u><em>so,18x6= 4x</em></u>
<u><em /></u>
<u><em>4x/4=108/4</em></u>
x=27 logs
Answer:
Both methods give 1/(12x + 32)
Step-by-step explanation:
Given 1/4(x + 2x + 16 - 8)
First Method.
Summing the like terms of the quantities in the denominator we are building, then multipying the root by 4.
Adding like terms in the denominator
1/4(x + 2x + 16 - 8) = 1/4(3x + 8)
Multiply denominator byv4
= 1/(12x + 32)
Second Method.
Multiply the quantities in the denominator by 4, and add the like terms together.
Multiplying denominator by 4.
1/4(x + 2x + 16 - 8) = 1/(4x + 8x + 64 - 32)
Adding like terms in denominator.
= 1/(12x + 32)
76 / 100 = 0.76 , 0.76 x 45 = 34.2
