It depends on what happens to the price of the item during the sale which is not stated in your problem. So if it cost 6 dollars and goes on sale it should be 6 dollars.
We are given a triangle with dimensions of the three sides as :
first side: 10x+3x²-8 feet
second side: 12x feet
third side: (15x+4) feet
Now perimeter of triangle is given by:
Perimeter = sum of three sides
So adding the three sides:
Perimeter = 10x+3x²-8 + 12x +15x+4
combining like terms and simplifying:
Perimeter = 3x²+37x-4
Answer: The perimeter of park will be (3x²+37x-4) feet.
The coordinate of the mid-point of line segment GH will be (6.5, 3).
<h3>What is the midpoint of line segment AB?</h3>
Let C be the mid point of the line segment AB.
A = (x₁, y₁)
B = (x₂, y₂)
C = (x, y)
Then the midpoint will be
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
The endpoints of GH are G(10,1) and H(3,5).
Then the coordinate of the mid-point of line segment GH will be
(x, y) = [{(10 + 3) / 2}, {(1 + 5) / 2}]
(x, y) = (6.5, 3)

I am not positive on this but I believe the answer is 600/15 because you can then accurately see how many feet the submarine rises per hour.
Answer:
Part 4) AA Similarity Postulate
Part 5)
The congruent angles are
m<ACB=m<CED , m<ABC=m<CDE, m<BAC=m<DCE
The proportional segments are
Step-by-step explanation:
Part 4) we know that
If BC is parallel to DE
then
Triangles ABC and CDE are similar by AA Similarity Postulate ( the three interior angles are congruent)
so
m<ACB=m<CED ------> by corresponding angles
m<ABC=m<CDE -----> both angles measure is 90 degrees
m<BAC=m<DCE -----> the sum of the interior angles of a triangle must be equal to 180 degrees
If two figures are similar, then the ratio of its corresponding sides is equal
so
substitute the values
Find DE
In the triangle ABC
Applying Pythagoras Theorem
Find AC
Find CE
