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

weqwewe [10]

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

What's the difference between 126 1/4 78 2/3

Stels [109]

Difference means subtract, so we use subtraction:

*first we need to make the fractions have the same denominator

1/4 = 3/12
2/3 = 8/12

126(3/12) - 78(8/12)
*since the fraction in the first term is smaller than the second, make it improper

125(15/12) - 78(8/12)

now simply subtract:

125 - 78
= 47

15 - 8
= 7
* this is now (7/12)

now put them back together:

47(7/12)

That's the final answer!
