How do you simplify #12 + 3(4 + x)#?

Answer 1

Nathan Axel

# = 3x + 24 #

#12 + 3 ( 4 + x ) #

# = 12 + 3 * ( 4) + 3 * (x ) #

# = 12 + 12 + 3x #

grouping like terms:

# = 24 + 3x #

# = 3x + 24 #

To simplify the expression ( 12 + 3(4 + x) ), follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). First, distribute the 3:

( 12 + 3(4) + 3x )

Then, perform the multiplication:

( 12 + 12 + 3x )

Finally, combine like terms:

( 24 + 3x )

So, ( 12 + 3(4 + x) ) simplifies to ( 24 + 3x ).
