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.
