Step-by-step explanation:
Her error is in squaring (2y)²
She has (2y)² = 2y²
when it should be 2y × 2y = 4y²
Then
(2y)² = 6² + 8²
4y² = 36 + 64
4y² = 100 ( divide both sides by 4 )
y² = 25 ( take square root of both sides )
y = 
= 5
Thirty four times 000 which I am assuming is just zeroes would be 0.
L x b x h
1 1/2 x 3/12 x 2/12
13 1/8. I THINK
After the distribution of x, you move 6 to the other side of the equation and then divide by three to get x=2. Therefore, the answer is c.
Hope this helps you!

<u><em>The correct answer is:</em></u>16%.
<u><em>Explanation</em></u><span>
<u><em>: </em></u>We use a z-score to answer this question.
<u>The formula for a z-score is:</u>
z=</span></span>
<span><span>,
where mue is the mean and sigma is the standard deviation.
<u>Using our information, we have:</u>
z=</span></span>
<span><span>.
Using a z-table, we see that the area to the left of, or less than, this score is 0.8413. We want to know how many students scored more than this, so we subtract from 1:
1-0.8413=0.1587, which rounds to 16%.</span></span>
