Answer:
C. 4 +√(x+5)
Step-by-step explanation:
The sign between the terms changes to form the conjugate. The radical contents are unchanged.
The conjugate of 4 -√(x+5) is 4 +√(x+5).
_____
<em>Additional comment</em>
The utility of a conjugate is that the product of a number and its conjugate is the difference of two squares. The squares are intended to remove an undesirable feature of the number, its imaginary part or its irrational part, for example. Here, the product of the number and its conjugate would be ...
(a -b)(a +b) = a² -b²
4² -(√(x+5))² = 16 -(x +5) = 11 -x . . . . no longer contains a root
2. m<-1.5
3. 11≥x
4. x≥1
5. x≥2

ANSWER 1
Note that,
is the same as
We apply the product rule.
So we keep the second function and differentiate the first,plus we keep the first function and differentiate the second.
Recall that,
If
Then,
This implies that,
ANSWER 2
We apply the product rule and the chain rules of differentiation here.
Recall that,
If
Then,
This implies that,
Yes, that is the correct answer. 27-12=15
