Answer:

x = 2.5

Step-by-step explanation:

For the equation:

$\frac{4}{2} = \frac{5}{x}$

The cross product is:

4 × x = 2 × 5

Solving for X

$x = \frac{2 * 5}{4}$

And reducing:

x = 2.5

Step-by-step explanation:

The difference of squares is defined as In option 1,

It can be written as

It is the sum of squares, therefore the option 1 is incorrect.

In option 2,

The number 40 is not a complete square of any number, therefore option 2 is incorrect.

In option 3,

It can be rewritten as

It is the difference of squares, therefore option 3 is correct.

Please answer! will give 5 stars, brainliest (if two people answer.), 20 pts, and thanks.

Charra [1.4K]

Answer:

Step-by-step explanation:

Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.

So angle 2 is 57.

Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:

57+57+angle 1=180

114+ angle 1=180

angle 1= 66

The function k(x) = (g x h)(x) is graphed below, where g is an exponential function and h is a linear function. If h(x) = x + 1,

2. Find the area in square meters of the figure below? Use 3.14 for. 6m

Illusion [34]

Answer:

in order to find the area, we should break up the figure. you can see that in the image we have a quarter of a circle and a square. here are the areas for each of these shapes

square:

$area = {x}^{2}$

circle:

$area = \pi {r}^{2}$

but since we only have a quarter of this circle we need to divide the area by 4 so the formula becomes

$\frac{\pi {r}^{2} }{4}$

now we can plug in our numbers

we are given 6 m for our radius or length of square

the square will be (6)^2 = 36 m^2

now onto our circle

π(6)^2/4 = 28.26 m^2

now add these two shapes together to find the total area = 64.26 m^2
