-x = -6 <br> please help me
Rasek [7]

Answer:

The answer would be positive 6

Step-by-step explanation:

I know it is -6 because when you solve this you do...

-x = -6

Divide both sides by -6

-x/-6 = -6/-6

the answer would be 6

because a negative divided by a negative is a positive.

Hope this helps have a great day! :)

Find xif 4; 4+2×;4+4× are in Geometric sequences​
Ray Of Light [21]

Given:

4,4+2x,4+4x are in geometric sequences​.

To find:

The value of x.

Solution:

If a, b, c are in geometric sequences​, then

\dfrac{b}{a}=\dfrac{c}{b}

b^2=ac           ...(i)

It is given that 4,4+2x,4+4x are in geometric sequences​. By using (i), we get

(4+2x)^2=(4)(4+4x)

4^2+2(4)(2x)+(2x)^2=(4)(4)+4(4x)

16+16x+4x^2=16+16x

4x^2=16+16x-16-16x

On further simplification, we get

4x^2=0

x^2=0

x=0

Therefore, the value of x is 0.

Line segments that have the same length are called similar segments. True or false?
guajiro [1.7K]

The statement that line segments that have the same length are called similar segments is false

<h3>How to determine the true statement?</h3>

The statement is given as:

Line segments that have the same length are called similar segments.

As a general rule:

Line segments that have the same length are similar segments.

However, line segments that have the same length are not called similar segments

Instead, line segments that have the same length are called congruent lines

This means that the the statement that line segments that have the same length are called similar segments is false

Hence, the statement that line segments that have the same length are called similar segments is false
