Answer:48x^15y^10z^4
Step-by-step explanation: multiply similar terms i.e 4×6×2=48
X×x^6×x^8=x^15
y×y^2×y^7=y^10
z^4×z^0=z^4
Answer:
Area=Length+height +breath
8cm+7cm+3cm+3cm
Area=21cm
Johnathan works part time on weekends at the movie theater while going to school during the week. His paycheck for this pay period was $225.

$225 + (-$225) = 0
0 is the answer when you add opposites
Answer:

Step-by-step explanation:
Here in this question, we want to calculate the mean absolute deviation of the data.
The first thing we will do here is to calculate the mean;
= (74 + 79 + 76 + 85 + 87 + 83 + 86 + 78)/8 = 81
Now, the next thing to do here is to calculate how far each of the values have deviated from the mean. This can be calculated by subtracting the mean from each individual value;
This is presented in the table on the attachment, please check attachment for this
Afterwards, we find the absolute value of all these subtractions then divide by 8 which is the number of values in the data.
Mean absolute deviation = Sum of all absolute deviations/number of values in dataset
