Answer:

  x = 35

Step-by-step explanation:

The marked consecutive interior angles are supplementary:

  (x +12)° +(4x -7)° = 180°

  5x +5 = 180 . . . . . collect terms, divide by °

  x + 1 = 36 . . . . . . . divide by 5

  x = 35 . . . . . . . . . . subtract 1

Find the product.<br> (z + 3i)(z − 3i)
Doss [256]

Answer:

First, we use distributive property:

(z+3i)(z-3i)=z^2-3zi+3zi-9i^2

Now, remember that i^2=-1, then

z^2-3zi+3zi-9i^2=z^2-9(-1)=z^2+9

Then,

(z+3i)(z-3i)=z^2+9
