All Real Numbers that are NOT Rational Numbers; cannot be expressed as
fractions, only non-repeating, non-terminating decimals
−√2 , −√5 3 , √21, √81 3 , √101
*Even roots (such as square roots) that don’t simplify to whole numbers are irrational.
Equivalent expressions are:
6x-3(3x-3)
-3(x-3)
-6x+3(3+3x)-6x
Step-by-step explanation:
We have to simplify each expression for comparison
Expression 1:

Expression 2:

Expression 3:

Expression 4:

Hence,
Equivalent expressions are:
6x-3(3x-3)
-3(x-3)
-6x+3(3+3x)-6x
