Calculate the value of \( 4(2x + 3) \) when \( x = 3 \).

Explanation:
To find the value of \( 4(2x + 3) \) when \( x = 3 \), start by substituting \( 3 \) for \( x \) in the expression: 1. Substitute \( x = 3 \): \[ 4(2(3) + 3) \] 2. Calculate the expression inside the parentheses first: \[ 2(3) = 6 \] Then add \( 3 \): \[ 6 + 3 = 9 \] 3. Now multiply this result by \( 4 \): \[ 4(9) = 36 \] Therefore, the value of the expression \( 4(2x + 3) \) when \( x = 3 \) is \( 36 \).

To find the value of ( 4(2x + 3) ) when ( x = 3 ), start by substituting ( 3 ) for ( x ) in the expression:

  1. Substitute ( x = 3 ):

[

4(2(3) + 3)

]

  1. Calculate the expression inside the parentheses first:

[

2(3) = 6

]

Then add ( 3 ):

[

6 + 3 = 9

]

  1. Now multiply this result by ( 4 ):

[

4(9) = 36

]

Therefore, the value of the expression ( 4(2x + 3) ) when ( x = 3 ) is ( 36 ).
