Answer: Convex

<h3 />

Step-by-step explanation  

The difference between convex and concave polygons lies in the measures of their angles. Another way to think of it is this: the diagonals of a convex polygon will all be in the interior of the polygon, whereas certain diagonals of a concave polygon will lie outside the polygon, on its exterior .Also If the interior angles of of the polygon are less than 180 degrees, then the polygon is convex. But if any one of the interior angles is more than 180 degrees, then the polygon is concave. T∴×∴T that was a lot

nikitadnepr [17]

Answer:

\frac{3}{4}

Step-by-step explanation:

  1. Find a common denominator for the 2 denominators: 6
  2. Change the fractions: 2 × 3 = 6, 1 × 3 = 3, 3 × 2 = 6, 2 × 2 = 4
  3. Re-write the fractions: \frac{3}{6} and \frac{4}{6}  
  4. Write as an expression: \frac{3}{6} ÷ \frac{4}{6}  
  5. \frac{3}{6} ÷ \frac{4}{6} = \frac{3}{6} × \frac{6}{4}
  6. \frac{3}{6} × \frac{6}{4} = \frac{18}{24}  
  7. \frac{18}{24} = \frac{3}{4}  

I hope this helps!
