Answer:
the common difference is 5.4 and yes, this is an arithmetic sequence
Step-by-step explanation:
Each new term is derived by adding 5.4 to the previous term:
2.1 + 5.4 = 7.5,
7.5 + 5.4 = 12.9,
and so on,
so the common difference is 5.4 and yes, this is an arithmetic sequence.
Take an example
14 / 20
the GCF of 14 and 20 = 2 ( 20 = 2^2 * 5 and 14 = 2*7 so 2 is the GCF)
so we can divide top and bottom of the fraction by 2 to give 7/10 = simplest form
Answer:
the answer is 3
Step-by-step explanation:
You can set up a ratio of side lengths as follows:

Now we just solve for x (by cross-multiplying):


So,
x = 75 units.
