Answer:
B. Side <em>a</em> is 7 inches long and side <em>b</em> is 6 inches long.
Step-by-step explanation:
Since the scale drawing is three times bigger than the actual object, divide both numbers by three to find the object size.
Side a:
21/3 = 7 inches
Side b:
18/3 = 6 inches
there are 4 eggs total 3 plain and 1 gold
so you have a 1/4 probability of picking the gold egg
Answer:


Step-by-step explanation:
The recursive rule is a term defined in terms of other terms in the sequence.
The is a geometric sequence because it has a common ratio.
The common ratio can be found by dividing a term by previous term.
For example, all of these are equal:



They are all equal to
.
So we are saying:

More formally:
.
Multiply both sides by
:

When doing recursive form, you need to state a term of the sequence (or more depending on the recursive form you have).
So the first term is 2.
So the full thing for the answer is:
