Answer:

-24

Step-by-step explanation:

Given expression:

      3z (2y - 4)²

  z = -2 and y = 3

To solve this problem, simply substitute:

       3z (2y - 4)² = 3(-2){2(3) - 4}²

                           = -6(6-4)²

                           = -6 (2)²

                          = -6 x 4

                          = -24

Jonah was standing at an elevation somewhere between-1 1/2
erma4kov [3.2K]

Answer:

=-\frac{23}{12},\ -2 and many others

Step-by-step explanation:

The limits given for Jonah's elevation with regards to sea level are

-1\frac{1}{2} and -2\frac{1}{3}

Any number belonging to that interval could be the requested answer. We'll pick the exact center (mean value) between them:

-1\frac{1}{2} =-\frac{3}{2}

-2\frac{1}{3}=-\frac{7}{3}

Computing the mean value:

\frac{1}{2}\left (-\frac{3}{2}-\frac{7}{3} \right)

=\frac{1}{2}\left (-\frac{23}{6}\right)

=-\frac{23}{12}

Since -2\frac{1}{3}=-2.33

And -1\frac{1}{2}=-1.5

Other numbers like -1.6,-2,-2,3 can be examples of the required answer
