Please help I am so confused lol. I’ll mark you the brainiest

ANTONII [103]

Answer:

Since the pentagon is regular, the line connecting the centre of the circle to the verticles (A,B,C,D,E) should inscribe an equal angle in them

You can see what I mean in the attachment

So to mark other points we follow the following steps

Connect OA
With OA as base, make angle of 72°. Say th new line is OB.
Similarly, do for the rest of them
This is a cyclic pentagon

If f(x) = 5x 6 and g(x) = x2 - 4x-8, find (f+ g)(x).

vredina [299]

The value of (f + g)(x) is x² + x - 14

Given: f(x) = 5x - 6

g(x) = x² - 4x - 8.

To find the value of (f + g)(x)

What are functions?

Functions are expressions or a rule that defines the relation between different variables which are described for a given problem.

Let's solve the question:

f(x) = 5x - 6

g(x) = x² - 4x - 8

We know from the algebra of functions that:

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = (5x - 6) + (x² - 4x - 8)

Now grouping like terms:

= x² + (5x - 4x) + (-6 - 8)

= x² + x - 14

Therefore, (f + g)(x) is x² + x - 14

Hence the value of (f + g)(x) is x² + x - 14

Find the missing length marked with a question mark.<br> UVW-USR

mariarad [96]

Given:

$\Delta UVW\sim \Delta USR$

To find:

The missing length marked with a question mark.

Solution:

Let x be the missing value.

We have,

$\Delta UVW\sim \Delta USR$

Corresponding sides of similar triangles are proportional, so

$\dfrac{UV}{US}=\dfrac{VW}{SR}=\dfrac{UW}{UR}$

Using this, we get

$\dfrac{UV}{US}=\dfrac{UW}{UR}$

On substituting the values, we get

$\dfrac{70}{x}=\dfrac{55}{44}$

$\dfrac{70}{x}=\dfrac{5}{4}$

On cross multiplication, we get

$70\times 4=5\times x$

$280=5x$

$\dfrac{280}{5}=x$

$56=x$

Therefore, the missing length is 56 units.
