x+9+2x3=x+15 and x+8+2x3
hope this helps! could i get brainliest plz?
The expressions to represent the dimensions of the outside border of the walkway is (x + 12) meters for the length and (x + 11) meters for the width.
Given area : [tex]x^2 + 17x + 72[/tex]
The factored form of the polynomial is:
[tex]x^2 + 17x + 72[/tex] = [tex]x^2 + 8x+9x+72[/tex]
= x(x+8)+9(x + 8)
=(x + 9)(x + 8)
So, the dimensions of the pool are (x + 9) meters and (x + 8) meters.
The length of the walkway = 3 meters wide
So, the length is added to each side of the pool.
Dimensions of the outside border of the walkway:
Length: (x + 9) + 3 = x + 12 meters
Width: (x + 8) + 3 = x + 11 meters
Therefore, the dimensions of the outside border of the walkway are
(x + 12) meters for the length and (x + 11) meters for the width.

Math problem A homeowner has two rectangular structures in her backyard. The dimensions of the hot tub are 6 feet by 8 feet. The dimensions of the fire pit are 7 feet by 9 feet. The length of the square backyard is 20 feet. What area of the yard is not covered by the hot tub and fire pit?
Answers
Answer:
289feet²
Step-by-step explanation:
Area of a rectangle = length x breadth
area of a square = length²
area of the yard that is not covered by the hot tub and fire pit =
Area of the yard - (area of the hot tub + area of the fire pit)
Area of the yard = 20 feet² = 400 feet²
area of the hot tub = 6 feet² x 8 feet² = 48 feet²
area of the fire pit = 7 feet² x 9 feet² = 63 feet²
400 - (48 + 63) = 289 feet²

Same goes for Angle Z and 5x+62.
[tex]z + 5x + 62 = 180 \\ 88 + 5x + 62 = 180 \\ 150 + 5x = 180 \\ 5x = 180 - 150 = 30 \\ x = 30 \div 5 = 6[/tex]

Answer:
FV= $3,672.07
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $3,200
Number of periods (n)= 4 years
Appreciation rate= 3.5% = 0.035
To calculate the price of the ring in four years, we need to use the following formula:
FV= PV*(1 + i)^n

A keypad has only the letters A-D what's is the total number of possible outcomes if the code has 3 letters
Answers
Answer:
The total number of possible outcomes if the code has 3 letters is 64
Step-by-step explanation:
The keypad has only the letters A-D, that is, A,B,C,D.
To calculate the total number of possible outcomes if the code has 3 letters,
let these spaces represent the code _ _ _
For the first space, there are 4 possibilities (since we have 4 letters)
For the second space, we also have 4 possibilities (since there is no restriction on repetition)
Also, we have 4 possibilities for the last space.
Hence, the total number of possible outcomes if the code has 3 letters is 4×4×4 = 4³ = 64.
There are 64 total possible outcomes if the code has 3 letters
The number of letters is given as:
n = 4
The code makes use of three letters.
This means that:
The first letter can be any of the 4 lettersThe second letter can be any of the 4 lettersThe third letter can be any of the 4 lettersSo, the number of possible outcomes is:
Outcomes = 4 * 4 * 4
Evaluate the product
Outcomes = 64
Hence, there are 64 total possible outcomes if the code has 3 letters

Step-by-step explanation:
The diagonal divides the rectangle into 2 right triangles.
The diagonal is the hypotenuse and the length l is a leg ( adjacent) to angle
Using the cosine ratio in the right triangle
cos22° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{l}{8}[/tex] ( multiply both sides by 8 )
8 × cos22° = l , then l ≈ 7.4 in ( to the nearest tenth )

Sixty percent of the water from the full bottle holding 1.5 L was used to fill 5 similar cups leaving no remainder. How much water does 1 cup hold ?
Answers
Answer:
0.9 of a Liter for the bottle's volume
0.18 L for each cut
180 mL for each cup.
Step-by-step explanation:
60/100 * 1.5 = 0.6 * 1.5 = 0.90
There were 5 cups
The volume of the bottle was 0.9 liters
1 cup held 0.9 / 5 = 0.18 L
1 Liter = 1000 mL
0.18 L = 1000 *0.18 = 180 mL

2.What is the slope-intercept form of a line that contains the points (5, - 5) and has a slope of -3?
3. Write an equation of a line that is parallel to y = - 5/2 x + 3 but travels through the origin? (Note: Parallel lines have the same slope.)
Answers
Answer:
2. y - (-5) = -3 (x - 5)
3. y = -5/2
Step-by-step explanation:
Point intercept form: y - y₁ = m (x - x₁)
Where y and x are just kept as y and x, y₁ and x₁ are the parts of a coordinate, and m = slope.
2. The points are (5, -5) and the slope is -3. Plug this into y - y₁ = m (x - x₁) to get
y - (-5) = -3 (x - 5)
3. As stated, parallel lines have the same slope, so the slope of the line would be -5/2. The origin is (0, 0), so plug these two numbers in.
y - y₁ = m (x - x₁)
y - 0 = -5/2 (x - 0)
y = -5/2
