Answer:
70 is answer
Step-by-step explanation:
Given that a function in x is

we have to find f'(7)
we know by derivative rule derivative of a function is

For finding out at 7 we replace x by 7

=
So f'(7) = 70
answer is 70
You must perform some cancellations to arrive at the final answer. I hope this helps
Answer: 18
Step-by-step explanation:
The least common denominator of
and
is going to be a multiple of 9 and 6. Let us list them out:
9: 9, <u>18</u>, 27, 36, 45, 54, 63, 72, 81, 90
6: 6, 12, <u>18</u>, 24, 30, 36, 42, 28, 54, 60
You can see I bolded and underlined 18. Why? This is the first common multiple of 9 and 6 so it is our least common denominator (LCD).
