Answer:
28 inch
Step-by-step explanation:
The length of all four sides of square is equal.
The formula used for finding the area of square is:
Area = (Length) × (Length)
Thus, the Area of square whose length is 2√7 is:
Area = 2√7 × 2√7
⇒ Area = 4 × 7 = 28 inch.

Hey there! :)
Answer:
f(15) = 29 ft.
Step-by-step explanation:
We can write an arithmatic equation for this pattern:
Where:
= 1, = 3
Find the rate of change. This is constant because this is an arithmatic sequence.
3 - 1 = 2.
We can begin to write an explicit function for this situation:
f(n) = + d(n-1) where d is the rate of change:
f(n) = 1 + 2(n-1)
Substitute 15 for n to solve for the distance traveled after 15 seconds:
f(15) = 1 + 2(15-1)
f(15) = 1 + 2(14)
f(15) = 1 + 28
f(15) = 29 ft.
Therefore, the distance traveled after 15 seconds is 29 ft.
