Answer:
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
