Answer: x = 12, y = 
Step-by-step explanation:
A 30-60-90 triangle has sides whose lengths are related. (shown in the diagram attached) The longest side, the hypotenuse (opposite the right angle) represents 2x. The shortest side is x, and the last side is 
.
We know the longest side = 24 = 2x.
If the shortest side is x, that means that the shortest side = the longest side DIVIDED by 2. Therefore, shortest side = x = 24/2 = 12 .
The last side is y and equals x\sqrt{3} . We now know that x = 12. Hence, y = .
Answer: B), the second one
Explanation: x is greater than or equal to 5

Answer:
See below
Step-by-step explanation:
The square root of a number is defined as ![\pm y=\sqrt[2]{x}](https://tex.z-dn.net/?f=%5Cpm%20y%3D%5Csqrt%5B2%5D%7Bx%7D)
where 
gives the original number. For example, 
because 
and

Answer:
The only possible answer that is correct is the first one, x = -4.
Step-by-step explanation:
Simplify the given inequality as much as possible, and then substitute each of the given x values one by one to determine which is in the solution set.
9(2x + 1) < 9x - 18 becomes 18x + 9 < 9x - 18, which, if reduced by dividing all four terms by 9, becomes 2x + 1 < x - 2.
Simplifying further, we get x < - 3. The only possible answer that is correct is the first one, x = -4. -4 < -3 is true.
