If UTV VU VU =US=SR by the hinge theorem.
UTV=UST=STR by the converse of the hinge theorem
UTV >UTS>STR by the converse of the hinge theorem

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
