Answer:

x=1

Step-by-step explanation:

Given: \frac{512^{x-2} }{(\frac{1}{64})^{3x}} = 512

To make this easier, we could change the base to a value of 2.

\frac{2^{9x-18} }{2^{-18x}} = 2^9

Move the denominator value to the numerator. When you do this, the -18x becomes positive, so you would add it to the value of 9x-18

2^{27x-18} = 2^9

Since the bases are equal to each other, that means the exponential values <em>must </em>be equal to each other.

27x-18=9

Solve for x.

27x=27

x=1

A square has a area of 466.56m squared work out the peremiter
MissTica

Answer:

Perimeter = 86.4 (m)

Step-by-step explanation:

A square (with side x) has an area of 466.56 (m^2)

=> x^2 = 466.56

=> x = sqrt(466.56) = 21.6

=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)

Hope this helps!

- What is the complete factorization of 4x2 – 24xy + 36y2 ?​
Rzqust [24]

<u>Answer: </u>

The complete factorization of 4 x^{2}-24 x y+36 y^{2} are 4(x-3y)(x+3y)

<u>Solution:</u>

Given Data:

4 x^{2}-24 x y+36 y^{2}

Take common value in all the three term.so we take 4 as common term in the above expression

4 x^{2}-24 x y+36 y^{2}=4\left(x^{2}-6 x y+9 y^{2}\right)

Now factorize the expression \left(x^{2}-6 x y+9 y^{2}\right)

Find the two numbers, whose product should be 9 and sum should be -6.

-3,-3 are the numbers which satisfy the above condition.

When we add -3-3=Sum is 6

Product of -3 \times -3= 9  

-3 , -3 satisfies the condition.

So the expression will become as x^{2}-6 x y+9 y^{2} = x^{2}-3 x y-3 x y+9 y^{2}

Take the common term

x(x-3y)+3y(x-3y)  

(x-3y)(x+3y)  

hence the complete factorization of 4 x^{2}-24 x y+36 y^{2} are 4(x-3y)(x+3y)
