This is tricky
lets try substituting y = √)6x - 9)
√(6 - y) + √(6x + y) = √6
squaring both sides:-
6 - y + 6 + y - 2√(6 - y)(6 + y) = 6
12 - 2√(6 - y)(6 + y) = 6
√(6 - y)(6 + y) = (6-12) / -2 = 3
Squaring both sides:-
(6 - y)(6 + y) = 9
36 - y^2 = 9
y^2 = 27
y = +/-√27
√(6x - 9) = +/- 27
6x - 9 = 729
x = 738/6 = 123
This cannot be a solution because we would have a negative value for the
second square root
I would say that no solution exist.

By definition of the trig functions,
We have 
, so 
, and 
, so 
.
Just to check: we should have
by the Pythagorean theorem. Indeed,
Answer:
B) f(x) and g(x) have the same domain but different ranges.
Step-by-step explanation:
The trick to this question is the find the least common multiple of 20 and 15. You could do 20×3=60 and 15×4=60 as those both equal the same number yet you there are no other multiples they share before 60. So the next time the two schools will eat pizza on the same day again will be in 60 days. Hope this helps!
