If the sol'ns are -9 and 9, then we can use this to form our eq'n:
(x - 9)(x + 9) = 0
x^2 - 81 = 0
so...
x^2 + z - 103 = x^2 -81
z - 103 = -81
z = -81 + 103
z = 22
24 is the answer because you have to muiltuple it
Add 8
C) 44, 52, 60

Answer:
If a number is a multiple of 2, it may NOT be a multiple of 4. An example would be the number 6.
, but
.
However, if a number is multiple of 4, it is guaranteed to be a multiple of 2, since 4 itself is a multiple of 2.
Example:

This is simply
.
It is a multiple of 2 twice.
Its already fully simplified.
