Answer:

[tex]-4[/tex]

Step-by-step explanation:

So we have the two functions:

[tex]h(x)=4x+5\text{ and } g(x)=3x+5[/tex]

And we want to find:

[tex](h+g)(-2)[/tex]

This is the same as:

[tex]h(-2)+g(-2)[/tex]

Let's substitute them for their functions:

[tex]=(4(-2)+5)+(3(-2)+5)[/tex]

Multiply:

[tex]=(-8+5)+(-6+5)[/tex]

Add:

[tex]=-3-1[/tex]

Subtract:

[tex]=-4[/tex]

And we're done!
