Unfortunately, due to the limitations of browsers, most mathematical symbols get removed and it leaves gibberish that is impossible to answer. At least I hope that mathematical operators have been removed, otherwise a string or characters without any real question is impossible to answer.

How do you write -3x2-x-30 in vertex form?
The vertex form is a(x - h) ² + k ....where (h,k) is the vertex -3x2 - x - 30 = -3(x2 + 1/3x + 10) . . . .now complete the square . . . . . . . . . . = -3[(x + 1/6))2 + 935/36] . . . and rearrange . . . . . . . . . .= -3(x + 1/6)2 - 2911/12
When h has the value 12 calculate 5h-2?
It is: (5*12)-2 = 58
What is the pH of a solution with H 7.0 10 12?
11.15
When h has the value of twelve culculate five h minus two?
5h means five times h - the times symbol is not written as it can be confused with a letter 'x': h = 12 → 5h - 2 = 5 x 12 - 2 = 60 - 2 = 58
What is the value of 2h-9when h equals 10?
When h=10, 2h-9 = 2(10)-9 = 20-9 = 11 .
