For the first question, simply plug in the value of 3 into the polynomial question. The final answer is your volume of the hot water tub.
For the second question, you can figure out that x = -5 is not a real root because it does not touch or cross the x axis.
If it does it would be an solution.
Answer:

Step-by-step explanation:
The angle marks mean those angles have the same measure. That means the sides opposite them have the same measure, so ...
2x -24 = x -2
x = 22 . . . . . . . . . add 24-x
The length of BC is x, so is 22.
BC = 22

Choice (A)
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
The absolute value of a negative number will switch to a positive when the indicators are removed.
Solve:
(3x-2)^2-4x(2x-3)>=0
(3x-2)(3x-2)-8x^2+12x>=0
9x^2-12x+4-8x^2+12x>=0
The solution: x^2+4>=0
