  • First of all, a 2 foot kangaroo is casting a 7 foot shadow.
  • Next we do 7 divided by 2 which equals 3.5.
  • Since we know the shadow is going to be 3.5x the object size we have to divide its shadow by 3.5
  • 14 divided by 3.5 is  4 so the Eucalyptus tree is 4ft long

<u><em>    Your answer=4ft </em></u>

<u><em></em></u>

Hope this helps!

Answer:

The answer to your question is below

Step-by-step explanation:

2. \sqrt{-128}                Just find the prime factors of 128 and simplify

   \sqrt{-2^{7}} = \sqrt{-2^{6} 2} = 2^{3}i \sqrt{2}

   8i\sqrt{2}

3.- \sqrt{-9} + \sqrt{-16}     Get the square roots and simplify

     3i + 4i

     7i

4.- None of the choices is equal to one, because the exponents are pair.

5.- 1/3x² + 10 = 7

    1/3x² = 7 - 10

    1/3x² = -3

         x² = -3(3)

         x² = -9

         x = ±3i
