We need to account for both x values on either side of the length, and width.
Thus, the length becomes 10 + x + x = 10 + 2x
and the width becomes 5 + x + x = 5 + 2x
For the second question, I'm assuming we don't account for the area that is covered by the garden.
Then we can say that the path is measured by: (5 + 2x)(10 + 2x) - 50, which is the area of the garden itself.
(5 + 2x)(10 + 2x) - 50 = 54
Expanding the brackets:
x = -9, or x = 3/2
Since x > 0, then x ≠ -9
Thus, the only x-value we can take is x = 3/2
Thus, the length becomes 10 + x + x = 10 + 2x
and the width becomes 5 + x + x = 5 + 2x

Answer:
61.1% of high school student who took the SAT in 2015 will have a critical reading SAT score between 400 and 600 points.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 495
Standard Deviation, σ = 116
We are given that the distribution of scores from the 2015 school year for high school students in the United States is a bell shaped distribution that is a normal distribution.
Formula:
P(SAT score between 400 and 600 points)
Thus, 61.1% of high school student who took the SAT in 2015 will have a critical reading SAT score between 400 and 600 points.
