The value of x = 2.5

The side length of the square = 7.1 units

<h3>How to Find the Perimeter of a Square?</h3>

A square has four congruent sides that are all of the same length. If "s" represents the length of one of the sides of the square., the formula that can be used to find the perimeter of the square is given as:

Perimeter of square = 4(s).

In the given image, we have the following:

Perimeter of the square = 28.4 units

Side length of the square (s) = 3.6x - 1.9

Therefore, we would create the  following equation using the perimeter formula:

4(3.6x - 1.9) = 28.4

14.4x - 7.6 = 28.4

14.4x - 7.6 + 7.6 = 28.4 + 7.6

14.4x = 36

14.4x/14.4 = 36/14.4

x = 2.5

Side length of the square = 3.6x - 1.9 = 3.6(2.5) - 1.9

Side length of the square = 7.1 units

Answer:

z =86

Step-by-step explanation:

The exterior angle of a triangle is the sum of the opposite interior angles

z + z-39 = z+47

2z-39 = z+47

Subtract z from each side

z-39 = 47

Add 39 from each side

z = 47+39

z =86

Wilson is thinking about buying a house. The table below shows the projected value of two different houses for three years.
statuscvo [17]
Given:
<span>                 Number of years 1               2            3 
House 1 (value in dollars) 249,000 253,980 259,059.60
House 2 (value in dollars) 249,000 256,000 263,000

House 1: exponential function
House 2: linear function

House 1: f(x) = 249,000 * (1.02)^(x-1)
</span>→ f(3) = 249,000 * (1.02)³⁻¹ = 249,000 * (1.02)² = 259,059.60

House 2: f(x) = 249,000 + 7,000(x-1)
→ f(3) = 249,000 + 7,000(3-1) = 249,000 + 7,000(2) = 249,000 + 14,000 = 263,000

House 1: 
f(45) = 249,000 * (1.02)⁴⁵⁻¹ = 249,000 * (1.02)⁴⁴ = 249,000 * 2.39 = 595,110

House 2:
f(45) = 249,000 + 7,000(45-1) = 249,000 + 7,000(44) = 249,000 + 308,000 = 557,000

House 1 will have a greater value than House 2 after 45 years.

Hi, please help me

Answer:

Perimeter: 22cm Area: 24cm^2

Step-by-step explanation:

To find perimeter we add all the sides together. There are two missing sides in this picture.

The bottom one is found by adding the two top lines 4 + 2 = 6

The one on the right can be found by subtracting the left line and the given right line 5 - 2 = 3.

Now we have all the lines, add them together we get 22cm!

Now, there are two ways to find the area. Of course I’m going to show the one I prefer.

Imagine the chunk in the top right is not missing; what would the area of the rectangle be? 30cm^2

And now what’s the area of the missing chunk?

Our given line multiplied by the one we calculated for: 6cm^2

Now subtract the whole rectangle minus the piece we are missing 30 - 6 = 24cm^2

What is the domain of the square root function graphed below?
fiasKO [112]

Answer:

The domain is [3,\infty).

Step-by-step explanation:

Domain is the input to a function. The input to a function is marked along the x axis as the x values are the independent values and thus are in the domain of the function.

From the graph, the function starts at x = 3 when the point is (3,1) and then the graph of the moves towards infinity.

So, the domain of the function starts at 3 and move towards infinity.

Hence, the domain include the x values between 3 to infinity including 3.

Find the value of A in the equation (5/a+3)=(3/A-2)
kolezko [41]
Solve for A:3 + 5/a = 3/A - 2
3 + 5/a = 3/A - 2 is equivalent to 3/A - 2 = 3 + 5/a:3/A - 2 = 3 + 5/a
Bring 3/A - 2 together using the common denominator A:(3 - 2 A)/A = 3 + 5/a
Multiply both sides by A:3 - 2 A = A (3 + 5/a)
Subtract (3 + 5/a) A + 3 from both sides:A (-5/a - 5) = -3
Divide both sides by -5/a - 5:Answer:  A = 3/(5 + 5/a)
