we want to expand the following expression:

well to do so we consider distributive property thus distribute:

reduce fraction which yields:

simplify Parentheses:

<h3>b)</h3>
in the expression there's a common factor of 4 therefore factor it out:

Answer:
There were total 4 samples collected and each sample had a sample size of n = 100.
Step-by-step explanation:
We are given the following information in the question:
Collection of samples:




Hence, there were total 4 samples collected and each sample had a sample size of n = 100.
The tens place because 4 and 8, 8 is over 5 so u round up then it is 254 rounded to the tens 55
The perimeter of a rectangle is twice the sum of length and width, so the sum of length and width is half the perimeter, 10 3/4 ft.
The width will be the difference between this and the length, hence 5 1/2 ft.
The area is the product of length and width.
A = length×width
A = (5.25 ft)×(5.5 ft) = 28.875 ft²
The area of the sandbox is 28 7/8 ft².
