Step-by-step explanation:

h(x) is positive when h(x) is greater than 0.

When h(x) = 0, 2x + 10 = 0, x = -5

Since this is a straight line graph and the gradient is positive, the interval is (-5,∞).

Cetacea

The interval is: [tex]\left(-5,\infty\right)[/tex].

If h(x) is positive then h(x)>0.

[tex]2x+10>0\\2x>-10\\x>-5[/tex]

So the interval is: [tex]\left(-5,\infty\right)[/tex].
