Answer 1

Correct option is:

D.
`23x^3+14x`

Explanation:

We have to find the sum:

`19x^3+(14x+4x^3)`

Combining the like terms, we get

`(19+4)x^3+14x`

=
`23x^3+14x`

Hence, Correct option is:

D.
`23x^3+14x`

Answer 2

we can simplify an equation or expression by checking out the similar terms that is terms that have the same variables. In this case, there are two similar terms: 19 x3 and 4 x3. The sum is equal to 23 x3. Hence the answer is D.  23x3 + 14x
