alexgriva [62]

Answer:

  • x = 2

Step-by-step explanation:

<u>We know that</u>

  • The diagonals of a rectangle are of equal length
  • The diagonals bisect each other

<u>Considering the above we have:</u>

  • EG = HF = 2JF = 2JH

<u>Substitute the given values and solve for x:</u>

  • 24x - 8 = 2*(8x + 4)
  • 24x - 8 = 16x + 8
  • 24x - 16x = 8 + 8
  • 8x = 16
  • x = 16/2
  • x = 2

MATHEMATICS: can anybody help or show me how to do this. look at the picture i need help with question 3?
Alekssandra [29.7K]
It wants you to come up with three events. You'll place them on the line right above, where you think they would go.

For example, if your first event was "seeing a unicorn" you would plot it by "impossible." Some things have a fifty fifty chance, or are likely, like you finding a penny. Use any scenario you can think of. How likely is it that it would come true?
