what is x of the rectangle?

Answers

Answer 1

Answer:

x = 8

Step-by-step explanation:

Since this is a rectangle, we know that each corner's angle is 90 degrees. (The box thing at the bottom right shows this.)

Since the two angles that make up angle E sum up to 90, we can make an equation:

(9x - 6) + (2x + 8) = 90

11x + 2 = 90

11x = 88

x = 8

9g − g + 4g − 8g − 2 = 18
plz

Answers

Answer:

g = 5

Step-by-step explanation:

Combine like terms on the left side.

9g - g + 4g -8g = 4g

4g - 2 = 18

Add 2 to both sides.

4g = 20

Divide both sides by 4.

g = 5

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.

A traffic helicopter descends 107 meters to be 407 meters above the ground, as illustrated in the diagram to the right. Write an equation to describe the situation using h as the original height of the helicopter. What was the original height of the helicopter?

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

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

The linear function that represents the height of the plant after n weeks is:

[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.

The linear equation that represents how many more hours Kelley must work to afford the phone is 3x - 45 = 0

Functions and values

Functions 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
