Answer:
the answer is 3n
Step-by-step explanation:
correct
Answer:
Please check the explanation.
Step-by-step explanation:
Given
f(x) = 3x + x³
Taking differentiate



solving






now solving




Thus, the expression becomes


Thus,
f'(x) = 3 + 3x²
Given that f'(x) = 15
substituting the value f'(x) = 15 in f'(x) = 3 + 3x²
f'(x) = 3 + 3x²
15 = 3 + 3x²
switch sides
3 + 3x² = 15
3x² = 15-3
3x² = 12
Divide both sides by 3
x² = 4



Thus, the value of x will be:

9514 1404 393
Answer:
4/25
Step-by-step explanation:
Put the numbers where the letters are and do the arithmetic.

A² + b² = c² a and b are the legs and c is the hypotenuse.
7² + 24² = c²
49 + 576 = c²
625 = c²
√625 = √c²
25 = c

Answer: 41.832
Step-by-step explanation:
I like to write decimals without decimals when multiplying. for this I would do
3486 x 12 which equals 41832 then You would move the decimal up from 3 spaces from the 2 from 41832 which would put the decimal between the 1 and 8
