Step 1: Distribute

So it becomes 12+24x+6x-15x

Step 2: Combine like-terms!

Then it becomes 15x+12 (It's 15x because 24x+6x= 30x then "add" the last  -15x. 
(30+ -15 = 15)

Answer:

\frac{2}{x-4}

Step-by-step explanation:

\frac{2x+4}{x^2-2x-8}

Factor both the numerator and denominator

\frac{2(x+2)}{(x-4)(x+2)}

The x+2 's cancel out

The equation in its simplest form is \frac{2}{x-4}

Hope this helps!

Each square below represents one whole<br> What percent is represented by the shaded area?
Goryan [66]

Step-by-step explanation:

Both squares are 50% = 100% in total.

1 square= 50%

1/2 of a square= 25%

50+25= 75% I think i'm pretty sure that's the answer.

Answer:

  1. reflection across the origin
  2. rotation 180° about the origin
  3. reflection across the x-axis, and translation right 6 units

Step-by-step explanation:

The figure and its image are symmetrical about the origin, so the following three transformations are equivalent:

  1. reflection across the origin

  2. rotation 180° about the origin

  3. reflection across both x- and y-axes, in either order

__

The figure itself has left-right symmetry, so only one reflection is necessary to map the figure to its image: reflection across a horizontal line. Following that reflection, the image can be put into place by an appropriate translation. One such pair of transformations is ...

  4. reflection across the x-axis and translation 6 units right, in either order
