Which shows a perfect square trinomial?
group of answer choices

latex: 49x^2-70xy+10y^2 49 x 2 − 70 x y + 10 y 2

latex: 50y^2-4x^2 50 y 2 − 4 x 2

latex: 16x^2+24xy+9y^2 16 x 2 + 24 x y + 9 y 2

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

1/4 is the answer if i recall correctly.
