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.
(-3,0) and (5, -2)
slope = (0 + 2) /(-3 - 5) = -2/8
y - 0 = -2/8 (x + 3)
y = -2/8 x - 6/8
8y = -2x - 6
2x + 8y = - 6
Answer is
D. 2x + 8y = -6

Hi there!
"mph" stands for "miles per hour".
This means that the car travels 55 miles in 1 hour.
To find your answer, you'll need to use the cross product method :
55 miles → 1 hour
206.35 → x
(1 × 206.35) ÷ 55 = x
206.35 ÷ 55 = x
206.35 ÷ 55 = 3.751818...
206.35 ÷ 55 ≈ 3.75
0.75 × 60 = 45 minutes
Your answer is: It takes 3 hours and 45 minutes for the car to arrive at its destination.
There you go! I really hope this helped, if there's anything just let me know! :)
