The 2nd and 4th expressions are the appropriate ones. Both result in '0' which means that Kiana is on the ground floor of the building at the end.
The point (−3, 0) is on the x axis.
I know because the point show us that
X=-3 and y=0
That means that the point that we will graph is on the -3 of the x axis. We don’t have to worry about the y because it’s equal to 0.
I think the answer is $48
7.256 + 5.088 + 16.009 = 28.353
693.501 - 56.287 = 637.214
