Aadc is formed by reflecting aabc across line segment ac, as shown in the figure. if the length of ac is 4 units, the area of aadc is square units.

The average length of a king cobra is 3.7 m. the record length is 1.88 m longer than the average. how long is the record holder?

Y< 2x-3 y? mx+3 which value of m and which symbol result in the system of inequalities shown above having no solution? a) m=-2; > b) m=-1/2; < c) m=2; > d) m=2;
