The percent error of Shirley's estimate is 21.74%
<h3>Calculating pecent error</h3>
Given the following parameters
- Actual length = 23 inches
- Estimated length = 18in
% error = actual-estimated/actual * 100
% error = 23-18/23 * 100
% error = 500/23
% error = 21.74%
Hence the percent error of Shirley's estimate is 21.74%

Answer:
4xy
Step-by-step explanation:
List the prime factors of each term.
- 4xy = 2·2·x·y
- 8x^2y = 2·2·2·x·x·y
- 24x^4y^5 = 2·2·2·3·x·x·x·x·y·y·y·y·y
Identify a factor that appears in each list. Cross it off of each list and add it to your list of "output" factors. Repeat until you run out of factors that appear in all of the lists.
You should quickly determine that all of the factors of 4xy appear in both other lists. That is the GCF. When you have exhausted the factors of 4xy, there are no more possible common factors.
GCF = 4xy
Then the expression can be factored as ...
= 4xy·(1 +2x -6x^3y^4)
_____
<em>Additional comment</em>
If you use exponents to simplify writing repeated multiplication, you will find that the GCF has the factors with the lowest exponent. Here, the lowest power of 2 is 2^2 in 4xy; the lowest exponents of x and y are 1, also in that term.
