H= -1 here's why:

7 = 12 + 5h

-5 = 5h

Then you would divide the equation by 5 from both sides it would then look like:

-1 = h

Rewrite square root of -49-4

Nataliya [291]

Answer:

$\sqrt{53i}$

Step-by-step explanation:

We need to find $\sqrt{-49-4}$

We know that √-1 = i

Adding -49 and -4 and solving

$\sqrt{-49-4}\\\sqrt{-53}\\\sqrt{53i}$

Since 53 is not a perfect square so our answer is:

$\sqrt{53i}$
