Answer:
B
Step-by-step explanation:
Use the elimination method by adding the equations together:
5x - 2y = 4
3x + 2y = 12
---> 8x = 16
x = 2
Answer:
106.5 square units.
Step-by-step explanation:
See the attached diagram.
The pentagon ABCDE consists of three triangles namely Δ ABC, Δ ACD, and Δ ADE when we join the diagonals AC and AD.
So, Area of Pentagon ABCDE = Area of Δ ABC + Area of Δ ACD + Area of triangle Δ ADE.
⇒ Area of Pentagon ABCDE = (31.8 + 39.2 + 35.5) = 106.5 square units. (Answer)
Green: 2/9×100=22. 22%
Red: 4/9×100=44. 44%
Blue: 3/9×100=33. 33%
Probability: 22. 22%+44. 44%+
33.33%= 99.99%
100. 00-99. 99= 00. 01%
