ANSWER

The sum of the given expression is,

[tex]23 {x}^{3} +14x [/tex]

EXPLANATION

The given expression is

[tex]19 {x}^{3} + (14x + 4 {x}^{3} )[/tex]

This expression is the same as

[tex]19 {x}^{3} +1 (14x + 4 {x}^{3} )[/tex]

We expand the parenthesis to obtain,

[tex]19 {x}^{3} +14x + 4 {x}^{3} [/tex]

We group the like terms to obtain,

[tex]19 {x}^{3} + 4 {x}^{3} + 14x [/tex]

Let us now combine the like terms to obtain,

[tex]23 {x}^{3} +14x [/tex]
