Question

Evaluate 4 x^3 + 4x when x = 3

Answer 1

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.
