Rational numbers are whole integers w no fractions. bc the square root of 72 is not a whole number, it is irrational
The degree of a polynomial is the highest power of the polynomial.
The polynomial is 
The degree is given as:

The zero is given as:

Add 3 to both sides

From the question, we understand that the polynomial has a single zero.
So, the polynomial is:

Substitute 4 for n

Hence, the polynomial is

Answer:
all are Not Equivalent
Step-by-step explanation:
The coefficient of t³ in the target expression is -3. In order for that to be the result of simplifying any of the given expressions, they must have ( )^(t^3) in the denominator. None do, so none of the offered choices is equivalent to the given expression.
_____
The expressions simplify like this:

Answer:
C
Step-by-step explanation:
m = -3
y = mx +b
y = -3x + b
Plugin x = -1 and y = 4
4 = -3*(-1) +b
4 = 3 + b
4-3 = b
b = 1
y = -3x + 1
