Prove the triangles with the given vertices are congruent A (3,1), B (4,5), C (2,3)
D(-1, -3), E (-5,-4), F (-3,-2)

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.

The answer would be c.8(2)=16-16=0 -8(2)=16-16=0
