The dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0
<h3>How to determine the dimension</h3>
For the pool, we have that;
Let the width = x feet
Length = (x+8) feet
The pool alongside the walkway gives;
Width = x + 5 + 5 = (x + 10) feet
Length = x + 8 + 5 + 5 = (x + 18) feet
Total area of the pool with walkway = 950 square feet
Note that formula for area is given as
Area = length * width = 950
Equate the length and width
(x+18) × (x + 10) = 950
Using the FOIL method, we have;
(x × x )+ (x × 10) + (18 × x) + (18 × 10) = 950
x² + 10x + 18x + 180 -950 = 0
collect like terms
x² + 28x - 770 = 0
Thus, the dimensions of the pool would give a quadratic equation x² + 28x - 770 = 0

To find the median, we must list our numbers from least to greatest.
35, 73, 77, 84, 85, 115.
Now that we've done that, to find the median, cross out the smallest number with the largest number.
35, 73, 77, 84, 85, 115.
73, 77, 84, 85.
Keep doing this until you can no longer do so.
77, 84.
Uh oh, it seems we have no middle number.
Since we are only left with 77 and 84, average the two numbers.
To find the average, add the sum of the numbers and divide by how many numbers there were added.
77 + 84 = 161.
Since we summed two numbers, divide by 2.
161/2 = 80.5
Your median is 80.5.
I hope this helps!
Ratio of their volumes = a³ : b³
Ratio of their surface areas =
<u>Step-by-step explanation:</u>
Two square pyramids are similar with their edges are in the ratio of a : b.
Volume of a square pyramid with edge and h = a is given by the formula,
= =
Volume of a square pyramid with edge b and h = b is given by the formula,
= =
Ratio of their volumes = a³ : b³ since h/3 gets cancelled.
Total surface area of square pyramid with the edge a =
Total surface area of square pyramid with the edge b =
