Answer:
120
Step-by-step explanation:
Given information:
• 4x³ + 4x
• x = 3
To evaluate the expression further, plug in the given variable and simplify:
4x³ + 4x Replace x with 3.
4(3)³ + 4(3) PEMDAS - put 3 to the 3rd power.
4(27) + 4(3) Use the distributive property to get rid of the parentheses.
108 + 12 Add the two values.
120
The simplification of 4x³ + 4x when x = 3 is 120.
