9 (3+3) - (16-4) =
Can u plz explain the answer for me plz

42

Step-by-step explanation:

This is called PEMDAS: PEMDAS is the abbreviation of the term, "Please Excuse My Dear Aunt Sally" or, "Parenthese, Exponents, Multiplication, Division, Addition, and Subtraction."

9 (3 + 3) - (16 - 4)

3 + 3 = 6

If anything is by a parenthesis that means its multiplication.

9 x 6 - (16 - 4)

16 - 4 = 12

9 x 6 - 12

9 x 6 = 54

54 - 12 = 42.

12

Step-by-step explanation:

A polynomial is an expression that contains more than one number, letter, etc. so 12 is a monomial, because it only has one number. Hope this helps!!
