OK. I did it, and I have the solution.
_____________________________________
The length of the deck is (5 + 2x) .
The width of the deck is (4 + 2x) .
If the deck didn't have that big hole in the middle where the pool is,
then its area would be
(5 + 2x) · (4 + 2x) .
When you multiply that all out, you get Area = 4x² + 18x + 20
and the question tells us that the area of the whole big rectangle is 90 yds² .
So we can write
4x² + 18x + 20 = 90 .
Subtract 90 from each side: 4x² + 18x - 70 = 0
Divide each side by 2 : 2x² + 9x - 35 = 0
You can use the quadratic equation to solve that and find out that
x = 2.5 yards, and that's what the question is asking you.
___________________________________________________
That makes the deck 10 yds high and 9 yds wide.
Total area of the whole big rectangle, (deck + pool ), = 90 yds².

Answer:
414 acres.
Step-by-step explanation:
To answer this question we have to multiply the percent by the total acres.
Remember that when multiplying percents we have to move the decimal 2 places to the left.
So, the equation looks like this:
Therefore, there are 414 acres that are old-growth trees.
We can check our answer by dividing 414 by 69,000.
414/69000 = .006
.006 * 100 = .6

Answer:
Yes.
Step-by-step explanation:
Option B was correct because it said that x was less than 1 so one couldn't be an answer. Knowing that you would have to pick one with an open circle showing that 1 couldn't be it so that narrows down the options to b or c. The line goes in the direction of the less than arrow (<) so that would point to answer b.
