Help pls
GarryVolchara [31]

Answer:

x^2-6x

Step-by-step explanation:

Let's start by factoring the top, or numerator of the fraction.

x^3-7x^2+6x = x(x^2-7x^2+6) = x((x-6)(x-1))

Now, you can divide this by (x-1):

\dfrac{x((x-6)(x-1))}{(x-1)}=x(x-6)=\boxed{x^2-6x}

Question : A square game board is divided into smaller squares, each with sides one-ninth the length of the sides of the board.
bagirrra123 [75]

Answer:

Therefore the game board is divided into 81 smaller squares.

Step-by-step explanation:

Given that, there is a square game.

Consider x be length of one side the square.

The volume of the square is = side ×side

                                               =x² square units

Since the length of side of smaller square is one-ninth of the game board.

Then one side length of the smaller square is \frac19x units.

The area of a smaller square is =(\frac19x)\times (\frac19x)

                                                    =\frac{1}{81}x^2

Let a number of square is formed from the game board.

a ×The area of one smaller square= The area of game board.

According to the problem,

a\times (\frac{1}{81}x^2)=x^2

\Rightarrow a =\frac{x^2\times 81}{x^2}

\Rightarrow a= 81

Therefore the game board is divided into 81 smaller squares.
