Suppose QP ∥ NO , and that R, S, and T are the midpoints of QN , QO , and PO respectively. Prove: RT= 1/2 (QP+NO)

Pls will give brainliest and all p.s u can zoom in if u cant see plss

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]

Select the correct answer and solve for y
