9514 1404 393

Answer:

  -15, 3

Step-by-step explanation:

3|x+6| -7 = 20

3|x +6| = 27 . . . . add 7

|x +6| = 9 . . . . . . divide by 3

This resolves to two equations:

  x + 6 = 9

  x = 3 . . . . . subtract 6

and

  x + 6 = -9

  x = -15 . . . . subtract 6

The projected T. rex is about
dolphi86 [110]

Answer: scale\ factor=230

Step-by-step explanation:

You need to analize all the information given in the exercise.

You know that the actual height of the T-rex on the projector lens is the following:

actual\ height=2\ cm

The height of the projected T-rex is:

projected\ height=4.6\ m

Make the conversion from meters to centimeters:

projected\ heigth=(4.6\ m)(\frac{100\ cm}{1\ m})\\\\projected\ heigth= 460\ cm

Therefore, the scale factor will be:

scale\ factor=\frac{projected\ heigth}{actual\ heigth}

Finally, you must substitute values into the equation and then you must evaluate in order to find the scale factor of the projection. You get that this is:

scale\ factor=\frac{460\ cm}{2\ cm}\\\\scale\ factor=230
