In Lanberry, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 16 kilometers and the distance between the courthouse and the city pool is 34 kilometers, how far is the library from the community pool?

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

i agree because i see the other persons thinking is clear

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
