Question

What is the value of 4x to the third +4x if x is 4

Answer 1

The correct answer of
$4{x}^{2} + 4x$
if x=4 is 272.

to solve the equation if x equals 4, you must substitute the x of the 4.
$4( {4}^{3} ) + 4(4)$
then solve by order of operations.
solve what is inside the parentheses first
$4(64) + 4(4)$
then do the multiplication of the factors
$256 + 16$
then the final step, adding, to get the solution of 272
