<u>Given</u>:
The perimeter of a polygon is the sum of the lengths of the sides of the polygon.
Given that the sides of the polygon are x + 1, 3x - 2, 3x - 2, x + 1.
We need to determine the perimeter of the polygon.
<u>Perimeter of the polygon:</u>
The perimeter of the polygon can be determined by adding the lengths of the sides of the polygon.
Thus, we have;
Removing the parenthesis, we get;
Adding the like terms, we get;
Thus, the perimeter of the polygon is

Answer:
D
Step-by-step explanation:
<em>The statements are shown below:</em>
<em>A) She used the wrong number as a repeated factor and should have evaluated -2x2x2x2x2x2x2x2. </em>
<em>B) She used the wrong number as a repeated factor and should have evaluated -(8x8). </em>
<em>C) She misinterpreted the exponential form and should have multiplied -2 and 8. </em>
<em>D) She made a sign error when multiplying and should have had 256 as a final answer.</em>

The problem to simplify is:
Haley's steps are shown below:
Generally,
is actually "a" multiplied "b" times.
So, Haley wrote "-2" eight times multiplied together. That is okay.
Now,
We are dealing with negative numbers.
Haley wrote "-2" eight times, which is EVEN number of times, so the answer would be POSITIVE. But, Haley's answer is negative. Which is wrong. But "256" is right.
Haley's error is:
