Answer:
the total distance is 56 cm
Step-by-step explanation:
Given that the area of the bulletin board is 196 cm^2
Based on this, the total distance around the bulletin board is
But before that we need to find out the side
As the area of square is
= side^2
196 = side^2
So side = 14
Now there are four sides, so the total distance is
= 4 × 14
= 56 cm
Hence, the total distance is 56 cm

Answer:
6, 9, 12, 15
Step-by-step explanation:
Comparing the given formula to the formula for the general term of an arithmetic sequence, ...
an = a1 +d(n -1)
we see that a1 = 6 and d = 3. That is, the first term of the sequence is 6 and each term is 3 more than the last.
The first 4 terms are 6, 9, 12, 15.
