Hence:

The area of a square is calculated by squaring the length of the sides (multiplying by itself). Therefore, in order to find the length, you must find the square root of 225.
The square root of 225 is 15. Therefore, you length of each side is 15 feet.
p.s. I don't know how old you are, but I would recommend trying to memorise your square numbers up to

. I know I found that incredibly useful when it came to my exams last year (GCSEs)
Answer:


Step-by-step explanation:
Given
See attachment for graph
Solving (a): Increasing interval
To do this, we simply identify the interval at which the value of the graph increases.
The value has an increased interval between -2 and 1.5 (of the x-axis).
Hence, the increasing interval is:

Solving (b): Decreasing interval
To do this, we simply identify the interval at which the value of the graph decreases.
The value has decreased intervals between - infinity and -2 and also 1.5 and infinity (of the x-axis).
Hence, the decreasing interval is:

Step-by-step explanation:
The above sequence is a geometric sequence
For an nth term in a geometric sequence

where
n is the number of terms
a is the first term
r is the common ratio
From the question
a = 5
r = 10/5 = 2
Therefore the explicit formula for this sequence is
