I need help. What’s the equation

Which point lies on a circle with a radius of 5 units and center at p(6, 1)?

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]

State if the two triangles are congruent. if they are, state how you know?
