Question

Can some one please help me

Answer 1

Basically, all you have to do is substitue the terms given at the top.

x = -3

y = 6

z = -4

The first one will be set up like this:

(-3) + 6 + (-1) = 2

The second one will be set up like this:

-15 + (- -3) + 6 = -6

The third one will be set up like this:

3(-3) - 2(6) + (-4) = -25

The fourth one will be set up like this:

2(-4) - 3 (6) + 4(-3) = -38

The fifth one will be set up like this:

3 ( -3) + 2 (6) + (-4) = -1

The sixth will be set up like this:

(-3)(-4)

---------- = -1

-2 (6)

The seventh will be set up like this:

2 (6) (-4) - 3 (-3) = -39

Hope this helps! Have a good day/night! c:
