All you need to do is substitue -2 into the equation for x,
h(-2) = 3(-2) + 1 = -6 + 1 = -5
It would be 9 + x =16
To solve it, subtract 9 from both sides of the equal sign
So (9+x)-9=16-9
Which is x=7, so the answer is 7.
I think it would be 54 words per minute
36÷2=18 which is 1/3 of a minute so we multiply 18 by 3 to get how many words in one minute, 18×3=54
