This is a statement that is always true, forwards and backwards.
a) axiom b) definition c) postulate d) theorem

B) Definition is a statement that is always true forwards and backward.

Step-by-step explanation:

A definition is a statement which tells the meaning of the term. So, it has two parts 1)-term and 2)meaning of term. We can write it forward and backward.

For example:- We are writing definition of equality then we say " Equality is  the state of a group of people of being equal in rights and status."

If we write it in backward then we can write

" The state of a group of people of being equal in rights and status is called equality."

Therefore definition is a statement is always true forward and backward.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

60: 45 =12: 9 =4: 3 so the answer is 4: 3
