Geo is
an=a1r^(n-1)
2nd term is 12
4th term is 4/3
a2=a1r^(2-1)=12
a2=a1r=12
a4=a1r^(4-1)=4/3
a4=a1r^3=4/3
we have
a1r=12 and a1r^3=4/3
(a1r^3)/(a1r)=r^2=(4/3)/12=1/9
1/9=r^2
sqrt oth sides
1/3=r
the common ratio is 1/3
Answer:
x = 3/5
Step-by-step explanation:
4+4(x-2)=2(x+1)−x
Distribute
4+4x-8 = 2x+1-x
Rearrange and Simplify
4x - 4 = x + 1
Subtract x and add 4
3x = 5
Divide
x = 3/5
Answer:
uhhhhhh i.dk lol
Step-by-step explanation:
Answer:
Step-by-step explanation:
To factor a number means to break it up into numbers that can be multiplied together to get the original number:
Therefore, factors of 30 and 8
30: 2×3×5
8: 2×2×2
Then, the common factor is 2
Only 2 can be divided both 8 and 30.
If you need to know all the factor of 30 and 8
30: 1,2,3,5,6,15, and 30
8: 1,2,4 and 8
The average is 13 hope this helps :D
