The set of rational numbers is the set of real numbers which can be expressed in the form a/b where a and b are integers.
Rational numbers can also be identified as terminating or recurring decimal numbers.
The <span>display weights on a digital scale that shows each weight to the nearest half pound gives a terminating decimal number.
Hence, it is best described by the set of real numbers.

Answer:
2x^2 + 3x + 2
Step-by-step explanation:
Like terms must have exactly the same variables and exponents on the variables.
2x^2 is not a like term to any other term, so it cannot be combined.
3x is not a like term to any other term, so it cannot be combined.
3 and -1 have no variable, so they are like terms and can be combined.
2x^2 + 3 + 3x - 1 =
= 2x^2 + 3x + 3 - 1
= 2x^2 + 3x + 2
Answer:
18 inches, assuming that the height is the length of the TV screen.
Step-by-step explanation:
First off, the shape of a TV screen is a rectangle.
To get the area of a rectangle, the equation would be:
H * W = A
where H = height, W = Width, and A = area.
If we pluck in the values given in the question, we get:
H * 32 = 576
To find out H, we have to get rid of the 32.
To do that, we divide both sides by 32.
Therefore, the equation is now:
H = 18.
Thus, the height of the TV screen is 18 inches.
The Answer is b The numerical values of the circumference and area are equal.
