Can some one help please

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?
