Solve (x 9)2 = 25. apply the square root property of equality: isolate the variable. startroot (x 9) squared endroot = plus or minus startroot 25 endroot if x 9 = 5, then x = . if x 9 = –5, then x = .
Answers
When a positive sign is considered then the value of x is -4 and when a negative sign is considered then the value of x is -14.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The equatiuon is (x + 9)² = 25.
Take square root on both sides, then we have
(x + 9) = ±5
For positive signs, we have
x + 9 = 5
x = -4
For negative signs, we have
x + 9 = -5
x = -14

You plant a tomato plant in your garden. It starts at 8 inches tall. After 1 week, it grows to 11 inches tall. After two weeks, it is now 14 inches tall. After 3 weeks, the plant is 17 inches tall. Write a linear equation that represents this model. How tall is the tomato plant after 56 weeks?
Answers
Answer:
The tomato plant is 176 inch tall after 56 weeks.
Step-by-step explanation:
x ⇒ weeks and y ⇒ inch.
Week 0 the tomato plant starts at 8 inch tall, week 1 it grows to 11 inch tall, week 2 it grows to 14 inch tall, week 3 it grows to 17 inch tall, week 56 is ? inch tall. So, every week (x) the tomato plant grows 3 inch (y).
y = 3x + 8
y = (3 × 56) + 8
y = 168 + 8
y = 176 inch
[tex]h(n) = 8 + 3n[/tex]
Using the function, after 56 weeks, the height of the plant is of 176 feet.The linear model for the height after n weeks has the following format:
[tex]h(n) = h(0) + an[/tex]
In which:
h(0) is the initial height. a is the rate of change.Starts at 8 inches tall, thus h(0) = 8. Each week the height increases 3 inches, thus, a = 3, and the model is:
[tex]h(n) = 8 + 3n[/tex]
After 56 weeks, the height is of h(56), thus:
[tex]h(56) = 8 + 3(56) = 176[/tex]
176 inches tall after 56 weeks.

Kelley has to work 45 hours at her job to earn enough money to buy a phone. She works 3 hours each day. If she has worked x days, write a linear equation to represent how many more hours Kelley must work to afford the phone.
Answers
The linear equation that represents how many more hours Kelley must work to afford the phone is 3x - 45 = 0
Functions and valuesFunctions are expressions represented in terms of a variable.
From the question, we have the following
Total number of hours = 45
If she works 3 hours per day and has worked x days, the total number of hours she needs to work is 3x
Equating to the total hours wwill give:
3x = 45
3x - 45 = 0
Hence the linear equation that represents how many more hours Kelley must work to afford the phone is 3x - 45 = 0

Answers
Step-by-step explanation:
Its 514 because 107+407 is 514
Answer:
h = 514 meters
Step-by-step explanation:
If the helicopter descends 107 meters to then be 407 meters above the ground, then it was originally 107 meters above 407 meters.
h-107=407
add 107 to both sides
h = 107+407
h = 514

Write an expression for the area of a square with sides of length a + b.
Use the distributive property to fully expand the expression.
Show your work.
Area
Answers
Answer:
area = (a + b)² = a² + 2ab + b²
Step-by-step explanation:
let side length = a + b
area of a square = side length × side length
⇒ area = (a + b)²
= (a + b)(a + b)
= a² + ab + ab + b²
= a² + 2ab + b²
The fully expanded expression for the area of a square with sides of length a + b is a² + 2ab + b².
The area of a square is given by the formula: Area = side × side.
In this case, the side of the square is a + b.
Therefore, the expression for the area of the square is:
Area = (a + b) × (a + b).
To fully expand this expression using the distributive property, we'll apply the FOIL method (First, Outer, Inner, Last):
Area = a(a + b) + b(a + b)
= a² + ab + ab + b²
= a² + 2ab + b².
So, the fully expanded expression for the area of a square with sides of length a + b is a² + 2ab + b².

Answers
The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³
What is dilation?
Dilation is the increase or decrease in the size of a figure.
The cone has surface area 360π in² and volume 800π in^3. the cone is dilated, and the surface area of the dilated cone is 2,250π in^2.
Hence:
Scale factor² = dilated cone area / cone surface area
scale factor² = 2250π / 360π
Scale factor = 2.5
Volume of dilated cone = 2.5³ × 800π = 12500π in³
The dilated cone's with surface area of 2,250π in^2 has a volume of about 12500π in³
