Answer 2

Answer:

6

Step-by-step explanation:

The given expression is

$3+(-h)+(-4)$

On simplification, we get

$3-h-4$

On combining like terms, we get

$(3-4)-h$

$-1-h$

We need to find the value of given expression where $h=-7$.

Substitute $h=-7$ in the above expression.

$-1-(-7)$

$-1+7$

$6$

Therefore, the value of given expression is 6 where $h=-7$.
