Simplify the algebraic expression: x(x + 3) + x(2x - 4) + 6

marusya05 [52]

Step-by-step explanation:

$x(x + 3) + x(2x - 4) + 6$

First, let's distribute the $x$ variable to each term in the first parenthesis:

$x^{2} + 3x + x(2x - 4) + 6$

Next, let's distribute the $x$ variable to each term in the second parenthesis:

$x^{2} + 3x + 2x^{2} - 4x + 6$

Next, let's group like terms together:

$(x^{2} + 2x^{2}) + (3x - 4x) + (6)$

Finally, let's add or subtract like terms to get the result:

$3x^{2} - x + 6$

Heather is putting together a square bulletin board for her new room, and the area of the bulletin board is 196 cm2. What is the

DedPeter [7]

Answer:

the total distance is 56 cm

Step-by-step explanation:

Given that the area of the bulletin board is 196 cm^2

Based on this, the total distance around the bulletin board is

But before that we need to find out the side

As the area of square is

= side^2

196 = side^2

So side = 14

Now there are four sides, so the total distance is

= 4 × 14

= 56 cm

Hence, the total distance is 56 cm

Dilation is a transformation that changes the size of a shape.

The coordinates of point S" is: $(-\frac{3}{2},\frac{9}{2})$

The transformation rule is given as:

$D_0,_\frac{3}{2}(x,y)*D_0,_\frac{1}{2} (x,y)$

This above rule means that:

The shape is dilated by 3/2
The resulting shape is then dilated by 1/2

From the complete question, the coordinate of S is:

$S=(-2,6)$

Apply the first transformation; <em>i.e. multiply S by 3/2</em>

So, we have:

$S'=(-3,9)$

Apply the next transformation; i.e. multiply S' by 1/2

So, we have:

$S''=(-\frac{3}{2},\frac{9}{2})$

Hence, the coordinates of point S" is:
