Respuesta :

Answer:

17

Step-by-step explanation:

Given:

The given expression is.

[tex]3x+2[/tex]

We need to solve the given expression for [tex]x = 5[/tex].

Solution:

Rewrite the expression as.

[tex]f(x)=3x+2[/tex]

Substitute x = 5 in above expression.

[tex]f(5)=3(5)+2[/tex]

[tex]f(5)=3\times 5 + 2[/tex]

Now we multiply 5 with 3.

[tex]f(5)=15+2[/tex]

Now we add right side terms.

[tex]f(5)=17[/tex]

Therefore, The correct value of given expression is [tex]3x+2=17[/tex] for [tex]x=5[/tex].
