For this case we have the following expression:

[tex]4 \sqrt {5} +2 \sqrt {5}[/tex]

We can rewrite the expression by taking a common factor.

We have then:

[tex]\sqrt {5} (4 + 2)[/tex]

From here, add the expression within the parenthesis we have:

[tex]6 \sqrt {5}[/tex]

Answer:

The equivalent expression for [tex]4 \sqrt {5} +2 \sqrt {5}[/tex] is given by:

[tex]6 \sqrt {5}[/tex]

Option C
