Answer:
The percentage of error in the question is 75%.
Step-by-step explanation:
To find the percentage of error, we need to subtract the actual value from the value that was expected, divide the result by the expected value.
He predicted that the crop would produce 8 bushels so this is our expected value. The actual value, which is the number of bushels produced, is 14.
- If we make the calculation (14 - 8) / 8 = 6 / 8.
- And then multiply the result by 100 to find the percentage, (6 / 8) x 100 = 75.
So the percentage of error in the question is 75%.

Answer:
(a) Because the expression is not an equation
(b) Because the expression is an equation
Step-by-step explanation:
Solving (a): a + 2
The above expression can assume any value for a because it is not an equation.
Take for instance:
a = 2;
<em>The reason for this is because the expression is not an equation</em>
Solving (b):
The above expression can assume only value for b, and the value is:
This means that only will make the equation true.
<em>The reason for this is because the expression is an equation</em>

The measure of given angles are equal to each other because they are alternate exterior angles,
Answer:
(n - 3)(2) or 2(n - 3)
Step-by-step explanation:
The area of a rectangle is its length multiplied by its width. But which side is length is up to you; there are 2 choices!
If the side marked n - 3 is the length, then the side marked 2 is the width. the area is (n - 3)(2).
On the other hand, if the side marked 2 is the length, then the side marked n - 3 is the width. The area is 2(n - 3).
By the way, both those expressions are equivalent to 2n - 6.
