Answer: simplified expression is 3x+5
Explanation:
3(x+3)-4
-Distribute (multiply) 3 through parentheses to get
3x+9-4
-subtract the 9 and 4 to get
3x+5
That’s your solution to a simplified equation!!
Answer:
Check below, please
Step-by-step explanation:
Step-by-step explanation:
1.For which values of x is f '(x) zero? (Enter your answers as a comma-separated list.)
When the derivative of a function is equal to zero, then it occurs when we have either a local minimum or a local maximum point. So for our x-coordinates we can say

2. For which values of x is f '(x) positive?
Whenever we have

then function is increasing. Since if we could start tracing tangent lines over that graph, those tangent lines would point up.

3. For which values of x is f '(x) negative?
On the other hand, every time the function is decreasing its derivative would be negative. The opposite case of the previous explanation. So

4.What do these values mean?

5.(b) For which values of x is f ''(x) zero?
In its inflection points, i.e. when the concavity of the curve changes. Since the function was not provided. There's no way to be precise, but roughly
at x=-4 and x=4
D.
That is what i do 12 x 2 will equal 24 since the are 2 parallel sides like in a rectangle. and it will be the same concept on the other side 7 x 2 = 14 and 24 + 14 will equal 38
hope this helped and is how you are supposed to work it
Quotient refers to division:
(8/v)² ⇒ (8/v)(8/v) = 8*8 / v*v = 64/v²
When you raise a fraction to a power, you multiply the fraction by itself according to the power raised.
Then, do the usual steps of multiplying fractions.
1) multiply numerators.
2) multiply denominators
3) simplify fraction produced.
It helps to draw a picture.
