<u>Answer:</u>
Mary simplified an expression. 
is correct representation in scientific notation.
<u>Solution:</u>
Given that Mary simplified an expression and got 
for answer in scientific notation.
According to Angela, answer is incorrect. Need to find reason why Angela consider as incorrect scientific notation and find the correct answer.
Let’s understand what is scientific notation of any number.
Scientific notation is a way of representing number between 1 and 10 including 1 and excluding 10 multiplied by appropriate power of 10.
According to Mary’s simplification the number she is getting is 12.9 but in scientific notation, number must be in between 1 to 10
So is not correct scientific notation.
Now we got 1.29 which is in between 1 and 10 multiplied by 
Hence is correct representation in scientific notation.

Answer:
h = 14 units
Step-by-step explanation:
Given:
Area of parallelogram = 84 units²
base length = 6
height = h
Required:
The missing height
SOLUTION:
Area of parallelogram = base × height
Plug in the values into the equation
Thus:
84 = 6 × h
84 = 6h
Divide both sides by 6
84/6 = 6h/6
14 = h
h = 14 units
