Answer:
6+x
Step-by-step explanation:
An expression is a set of operations without an equal sign. This question is asking which operation is being performed. The question states that there should be six more than x, this means 6 is being added to x. So, addition should be used to make the expression.
First remove the parenthesis.
5/6 - 2/3
Then we want the least common denominator which is 6 because 2 * 3 = 6.
Now we want to adjust the fractions based on our LCD.
So 5/6 - 2 * 2/6
Now since the denominators are equal we can combine the numerators.
So 5 - 2 * 2/6
First multiply 2 by 2 to get 4. Our expression then becomes 5 - 4/6 which translates to 1/6.
Hope this helps!

Answer:
4a +4
Step-by-step explanation:
The average rate of change of f(x) on the interval is ...
(f(a) -f(1))/(a -1)
= ((4a² -6) -(4(1)² -6))/(a -1) = (4a² -4)/(a -1)
= 4(a² -1)/(a -1) = 4(a +1) = 4a +4
The average rate of change on the interval is 4a +4.
