8is subtracted from one-fourth of n

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.

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !

well in order to answer the question, you have to give us the dimensions of the prism first.
