Hello from MrBillDoesMath!
Answer:
sqrt(6)
Discussion:
The triangle, while not indicated, appears to be a right triangle (i.e. has a 90 degree angle). If so, from the Pythagorean theorem,
x^2 + 3^2 = ( sqrt(15) ) ^ 2 =>
x^2 + 9 = 15 => ( subtract 9 from both sides)
x^2 = 15 - 9 = 6 => (take the square root of both sides)
x= sqrt(6)

Answer:
Step-by-step explanation:
One solution: when two lines intersect in exactly one point.
Infinitely many solutions: When one of two lines can be shown algebraically to be exactly the same as the other. The two lines coincide.
No solution: The two lines have the same slope but different y -intercepts. They can't and don't intersect.
The right answer is, 18+14.

Answer:
12.686cm
Step-by-step explanation:
By using pythagoras, we can find CB.
We know that 
Therefore, 
(it has to be positive since it is distance)
now we look at triangle BCD and use SOH CAH TOA.
