Answer:
-8x^2·y·z +3y·z^2 -4y
Step-by-step explanation:
It can be helpful to make sure the variables in each term are in alphabetical order. This makes it easier to see "like" terms. The variables in each term are ...
x^2 y z
y z^2
x^2 y z
y
Only the first and third terms are like terms, so those are the only ones that can be combined. Their coefficients are -7 and -1, so sum to -8. The combined term is of highest degree, so in standard form we list that term first.
= -8x^2·y·z +3y·z^2 -4y
-48 is the answer to the question
mean = Summation of Data/Number of Data Added
mean = [(-54)+(-32)+(-70)+(-25)+(-65)+(-42)] / 6
mean = -288 / 6
mean = -48
Answer:5
Step-by-step explanation:33 + 5 =38 * 6= 228
