Answer:
D.−√5
Step-by-step explanation:
4 sqrt(20) -3 sqrt(45)
We know that sqrt(ab) = sqrt(a) sqrt(b)
4 sqrt(4) sqrt(5) - 3 sqrt(9) sqrt(5)
4 *2 sqrt(5) - 3 *3 sqrt(5)
8 sqrt(5) - 9 sqrt(5)
- sqrt(5)
Triangle:
39 degrees, 33 degrees, 108 degrees
Side opposite the 108 degrees is 360 feet.
length asked for is d

Step-by-step explanation:
Apparently you want to simplify ...

The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
1/a^b = a^-b
(a^b)^c = a^(bc)
__
So the expression simplifies as ...
