Answer:

The length of the other segment is longer than 7 units

Step-by-step explanation:

we know that

The<em> i</em><u><em>ntersecting chords theorem</em></u> states that the products of the lengths of the line segments on each chord are equal

see the attached figure to better understand the problem

Remember that the diameter of the circle is two times the radius

D=2(9)=18\ units

Let

x ----> the length of the other segment

so

(9+5)(4)=(7)(x)

56=7x\\x=8\ units

therefore

The length of the other segment is longer than 7 units

3x-5=2(2x+5) how do you slove it
DaniilM [7]

Answer:

x = -15

Step-by-step explanation:

3x-5=2(2x+5)

Expand by using distributive property

3x - 5 = 4x + 10

Subtract 4x from both sides

3x - 5 - 4x = 4x + 10 - 4x

Simplifying

-x - 5 = 10

Add 5 to both sides

-x - 5 + 5 = 10 + 5

Simplifying

-x = 15

Divide both sides by -1

x = -15

How do i add and subtract polynomials?<br>(4v-6v)-(v-5v^3)+(5v^3+4)
Ksenya-84 [330]
Distribute and add like terms and you are good

alirghty

we can make it easier by simplifying what we can

(4v-6v)=-2v so

(-2v)-1(v-5v³)+(5v³+3)=
-2v-v+5v³+5v³+3=
10v³-3v+3
