Answer:

Option A.

Step-by-step explanation:

The given expression is

[tex]3a+6b[/tex]

We need to find the value of given expression when a=5 and b=-2.4.

Substitute a=5 and b=-2.4 in the given expression.

[tex]3(5)+6(-2.4)[/tex]

[tex]15+(-14.4)[/tex]

It can be written as

[tex]15-14.4[/tex]

[tex]0.6[/tex]

Therefore, the value of given expression is 0.6 when a=5 and b=-2.4.
