Answer:

x = 3

Step-by-step explanation:

8x - 12 = 4x ( subtract 4x from both sides )

4x - 12 = 0 ( add 12 to both sides )

4x = 12 ( divide both sides by 4 )

x = 3

What is 1/x^2 in the power of x

Serhud [2]

we have given that $\frac{1}{x^2}$ .

we need to express this interms of power of x .

we know that $\frac{1}{x^n} =x^-n$ .

in place of n we have 2 .so $\frac{1}{x^2} =x^-2$ .

so this will be the expression interms of power of x .

Answer:

See Explanation

Step-by-step explanation:

The question has unclear information.

So, I'll answer from scratch

Given

ABC = Right angled triangle

DB bisects ABC

Required

Prove that CBD = 45

From the question, we have that:

ABC is right angled at B

So, when DB bisects ABC, it means that DB divides ABC into two equal angles.

i.e.

$CBD = ABD$

and

$CBD + ABD = 90$

Substitute CBD for ABD in $CBD + ABD = 90$

$CBD + CBD = 90$

$2CBD = 90$

Divide both sides by 2

$\frac{2CBD}{2} = \frac{90}{2}$

$CBD = \frac{90}{2}$

$CBD = 45$

Hence, it is proved that $CBD = 45$

Follow the above explanation and use it to answer your question properly
