Answer:
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
Step-by-step explanation:
use the formula an=a1rⁿ⁻¹
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
Answer:
D
Step-by-step explanation:
E. 3/12 is equivalent to 1/4, which is the ratio of the cylinders.
Remark
You have to read this carefully to know what way to write it.
One way you could write it would be
20 * x = 18 where x is the fraction. Now all you need do is divide.
Divide both sides by 20
20/20 * x = 18/20

But you should reduce this fraction. The way to do that is to factor 18 and 20 into primes.
18: 2 * 3 * 3
20: 2 * 2 *5
Cancel out the Highest common factor or 2.
You are left with
