Choose an
-4.5
13.5
4.5
-13.5

the answer isn't part of non of the above the answer is -1.5

Step-by-step explanation:

Mark this as brainlest

4.5

Step-by-step explanation:

I am assuming s3 means s raised to the 3 power.  I hope that is the correct assumption.  If you plug in the values for s and t you will get this equation:

-3[5 - (2)(2)(2)] + 3(-1.5) you can simplify this more

-3[5 - 8] + (-4.5)  and even further

-3[-3] + (-4.5)

negative 3 times negative 3 equals positive 9

adding a negative 4.5 is the same as just subtracting 4.5 so now it looks like this:

9 - 4.5 which equals 4.5

i got 86 for this

hope this !
